Statistics is the science of conducting studies to gather, organize, summarize, and figure out the conclusion from the data.

The science of studies in statistics involves below points :

1. Collection of data is a systematic process of gathering information from relevant sources to conclude the research problem. Example: Survey and questionnaire case studies.

2. Organization of data involves arranging the primary or raw data in an understandable and cauterized order. It includes the process of classification, picture and graphic representation and frequency distribution table. Example: organising marks scored by students in different subjects.

3. Summarizing is the method of outlining and providing information regarding our research data, it draws the value of our data.

4. Analysis is another way of statistics involving the science of collecting data and uncovering patterns and trends in it. Example: making of pie charts.

5. Conclusion is the final stage in the science of statistics studies it results in finding the answers to our research questions. Example: a survey on youth and politics, conclusion: 60 % of youth have no interest in politics.

Answer:

Step-by-step explanation:

V=4

3πr3=4

3·π·93≈3053.62806

Answer:

3053.62548 m^3

Step-by-step explanation:

Answer:

See the explanation below.

Step-by-step explanation:

n = sample size = 1000

X = proportion of adults that a will = 450 / 1,000 = 0.45

P-value = 0.5

a = level of significance = 5%, or 0.05

A. At the 5% significance level, can you conclude that the percentage of people who have a will is less than 50%?

Our hypotheses are:

Null hypothesis: u ≥ 0.5

Alternate hypothesis: u < 0.5

Since this indicates a left tailed test, the decision rule is to reject null hypothesis if p-value is less than the level of significance.

\(Z = test statistic = \frac{0.45 - 0.5}{0.5/\sqrt{1,000} }\)

Z =  - 0.05 / 0.0158113883008419 = - 3.1623

Using the excel function NORMSDIST(-3.1623), we have:

P- value = 0.000782701129001276, approximately 0.0008

Therefore, null hypothesis is rejected at 5% level of significance since the p-value 0.0008 is less than 5%, or 0.05.

Therefore, there is an enough reason to reject null hypothesis.

B. What is the Type I error in part A? What is the probability of making this error?

Since the probability is greater than 50%, the Type I error is therefore the statement in the question that less than 50% of adults have a will.

Also, the probability of making this Type I error is the 5% level of significance.

C. What would your decision be in part A if the probability of making a Type I error were zero?

The null hypothesis will be rejected if the probability of making a Type I error were zero in part A.

We use ANOVA to test for differences between population means by examining the amount of variability between the samples relative to the amount of variability within the samples. Hence, it is TRUE

The statistical analysis tool known as analysis of variance (ANOVA) divides the observed aggregate variability present in a data set into two categories: systematic variables and random components. The random factors have no statistical impact on the presented data set, whereas the systematic factors do. The ANOVA test is used by analysts to ascertain how independent factors in a regression analysis affect the dependent variable.

ANOVA basically stands for analysis of the variance.

The solution set of the equation x/3 = 8/(x + 2) when calculated is x = -6 or x = 4

Given the following equation

x/3 = 8/(x + 2)

Cross multiply

x(x + 2) = 24

To find the solution set of x(x + 2) = 24, we need to solve for x by simplifying the left-hand side of the equation and then factoring it.

x(x + 2) = 24

Expanding the left-hand side, we get:

x² + 2x = 24

Subtracting 24 from both sides, we get:

x² + 2x - 24 = 0

Now we can factor the quadratic expression on the left-hand side:

(x + 6)(x - 4) = 0

Using the zero product property, we know that the product of two factors is zero if and only if at least one of the factors is zero.

Therefore, we can set each factor equal to zero and solve for x:

x + 6 = 0 or x - 4 = 0

Solving for x, we get:

x = -6 or x = 4

So, the solution set is { -6, 4 }.

These are the values of x that make the equation true when plugged in.

Answer:

How are we supposed to know .???

we can only see half of the problem

Step-by-step explanation:

If earth days merely 2 hours long, which means the rotation period of the earth is 2 hours, your weight will become 1/144 of your actual weight.

The weight or gravitational force on a mass can also be considered as centripetal force.

The formula for the centripetal force is:

F = m v²/R

In this case,

m = your mass

v = tangential velocity or earth's rotation speed

R = earth's radius

Recall that speed = distance / time. In the problem, the distance is the circumference of the earth and the travelled time is the rotation period.

v = C/t

t₁ = 24 hours

t₂ = 2 hours

Since the units are the same, we do not need to convert the unit when comparing them.

Notice that the centripetal force is directly proportional to the square of rotation speed.

F ∝ v²

Hence,

F₁ : F₂ = v₁² : v₂²

But v is inversely proportional to rotation period. Hence,

F₁ : F₂ = t₂² :  t₁²

F₁ / F₂ = (t₂ /t₁)²

F₁ / F₂ = (2 /24)²

F₁ / F₂ = (1 /12)²

F₁ / F₂ = 1/144

Hence, your weight will be 1/144 of your actual weight.

Answer:

2c+b-w   It is a trinomial.

Step-by-step explanation:

Making the equation is pretty easy. Since you get 2 points for corrent answers, we can write down 2c. You get one point for blank, so you can write down 1b, or just b. And, since you get -1 point for each incorrect answer, you can write down -1w, or just -w.

So, if you put the equation together, you will get 2c+b-w for the equation.

Since this equation have 3 terms (2c, b, and w) seperated by the + and -, we know that it is a trinomial.

The probability that both students are girls is 3/10 or 0.30 if Mr. Garcia has 11 boys and 14 girls in his math class. He selects two students at random to demonstrate how they solved the day’s challenge assignment.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

We have:

Total number of boys in Garcia's math class = 11

Total number of girls in Garcia's math class = 14

Total number of students = 11+14 ⇒ 25

Total number of outcomes = \(_{25}C_{2}\)

Total number of favorable outcomes = \(_{14}C_2\)

Now, the probability,

\(=\frac{_{14}C_2}{_{25}C_2}\)

The value of \(_{25}C_{2}=300\)

The value of \(_{14}C_2=91\)

\(=\frac{91}{300}\)

= 3/10 or 0.30

Thus, the probability that both students are girls is 3/10 or 0.30 if Mr. Garcia has 11 boys and 14 girls in his math class. He selects two students at random to demonstrate how they solved the day’s challenge assignment.

The grower should plant 59 trees per acre to maximize her harvest, and the maximum harvest she can achieve is approximately 3540 bushels.

To determine the number of trees the plum grower should plant per acre to maximize her harvest, we can set up an equation and use calculus to find the optimal solution. Let's denote the number of additional trees planted as x.

The yield of each tree can be represented by the equation:

Yield = 126 - 2x

The total yield per acre is then given by:

Total Yield = (26 + x) * (126 - 2x)

To maximize the harvest, we need to find the value of x that maximizes the total yield. We can achieve this by finding the maximum point of the quadratic equation representing the total yield.

Differentiating the equation with respect to x and setting it equal to zero, we can find the critical point:

d(Total Yield)/dx = -4x + 252 - 2(26 + x) = 0

Simplifying the equation, we get:

-4x + 252 - 52 - 2x = 0

-6x + 200 = 0

x = 200/6

x ≈ 33.33

Since we cannot have a fraction of a tree, the grower should plant 33 additional trees per acre to maximize her harvest. This gives a total of 26 + 33 = 59 trees per acre.

To find the maximum harvest, we substitute the value of x into the equation for the total yield:

Total Yield = (26 + 33) * (126 - 2 * 33)

Total Yield ≈ 59 * 60

Total Yield ≈ 3540 bushels

Therefore, the grower should plant 59 trees per acre to maximize her harvest, and the maximum harvest she can achieve is approximately 3540 bushels.

The volume of Ganymede is approximately 3.48 times the volume of the Moon, based on the given diameters of the two moons and the formula for the volume of a sphere.

The volume of a sphere is the amount of space occupied by the sphere in three-dimensional space. It can be calculated using the formula V = (4/3)πr³, where V is the volume of the sphere, r is the radius of the sphere, and π (pi) is a mathematical constant approximately equal to 3.14159. This formula states that the volume of a sphere is four-thirds of the product of pi and the cube of the sphere's radius.

In the given question,

The volume of a sphere can be calculated using the formula V = (4/3)πr³, where r is the radius of the sphere. Since we are given the diameters of the two moons, we can calculate their radii by dividing the diameters by 2. Therefore, the radius of Ganymede is 3,388/2 = 1,694 km, and the radius of the Moon is 1,245/2 = 622.5 km.

Now, we can calculate the volumes of the two moons:

V_Ganymede = (4/3)π(1694)³ ≈ 7.66 x 10^10 km³

V_Moon = (4/3)π(622.5)³ ≈ 2.2 x 10^10 km³

To find how many times larger Ganymede's volume is compared to the Moon's volume, we can divide the volume of Ganymede by the volume of the Moon:

V_Ganymede / V_Moon ≈ (7.66 x 10¹⁰) / (2.2 x 10¹⁰) ≈ 3.48

Therefore, the volume of Ganymede is approximately 3.48 times the volume of the Moon.
