D. Reject H0; stress affects the menstrual cycle.

Step-by-step explanation:

Samples:

High stress 20 23 18 19 22

Relatively stress free 26 31 25 26 30

Using calculator :

Mean, x1 = 20.4 ; n = 5 ;

Standard deviation, s1 = 2.07

Mean, x2 = 27. 6; n = 5 ;

Standard deviation, s2 = 2.70

The test statistic :

(x1 - x2) / sqrt[(s1²/n1 + s2²/n2)]

(20.4 - 27.6) /sqrt[(2.07²/5 + 2.7²/5)]

-7.2 / 1.523 = - 4.73

Df = n1 + n2 - 2

df = 5 + 5 - 2 = 8

From t-value distribution :

df = 8 ; α = 0.052

Tcritical = +- 2.306

|Tstatistic | > | Tcritical | ; Reject H0

Answer:

The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.

Step-by-step explanation:

A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.

Time is the number of hours, so it is mean, and not proportion.

Variable of interest is time to complete the round, and since it is measured in hours it is a quantitative variable.

The answer is:

The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.

The confidence interval for a population of variable of interest time is normally distributed  . The Confidence interval for proportion mean should be constructed because the  variable of interest is the time taken to complete one round of golf score, time to complete the round.

Whether the round was completed in less than 5 hours or not is depending upon the calculations involved and variables  of  the sample taken which is a  quantitative variable.

The confidence interval for the normally distributed variable of interest is determined by the equation as formulated below

\(\rm Confidence\; Interval = \mu - Z \sigma/\sqrt{n} \;\;to \; \mu + Z \sigma/\sqrt{n} \\Where\\\mu = Sample\; mean \\Z = Z \; score \\\\\sigma = Sample\; standard \; deviation \\n = Sample \; size\)

We have to  indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variable of interest.

A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.

The goal of the research was to estimate the amount of time  it typically takes to complete a round of golf on Saturday morning

As given by the language of the question we can conclude that the variable of interest is the time taken to complete one round of golf.

So we consider that the time variable is normally distributed

Also time variable is quantitative variable.

So we can fill in the blanks

The confidence interval for a population of variable of interest time is normally distributed .The Confidence interval for  proportion mean should be constructed because the  variable of interest is the time taken to complete one round of golf score, time to complete the round.

Whether the round was completed in less than 5 hours or not is depending upon the calculations involved and variables  of  the sample taken which is a  quantitative variable.

Answer:

  11 years, 7 months

Step-by-step explanation:

When the investment reaches its desired value, it will be 3 times the original amount. So, we are looking for the number of half-month periods (n) of compounding such that ...

  (1 +0.095/24)^n = 3

Taking logarithms, we have ...

  n·log(1.003958333...) = log(3)

  n = log(3)/log(1.009358333...) ≈ 278.09

This is 278.09/24 ≈ 11.59 years.

It will take about 11 years and 7 months for the investment to reach the desired value.

Commutativity justifies the statement, of If n is a multiple of 8, then n is even. However, n is not even. Therefore, n is not a multiple of 8.

Commutativity is used in Maths equations and describes sums that can be moved around and will still give the same answer.

'Commutative' comes from the word 'commute' which means to move and travel around, so equations that are commutative have numbers that can be moved within the equation.

Answer:

What is the expected value for the insurance company?

E(x) = 0.9986*161 + 0.0014*(-99839) = $21.00

Step-by-step explanation: Ur welcome

There is a 0.9986 probability that a randomly selected 30 year old male lives through the year. A life insurance company charges $161 for insuring that the male lives through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit.

Answer:

a. The probability that all 5 selected transistors are defective is 0.0024 or 0.24%.

To calculate this probability, we use the formula for the probability of the intersection of independent events:

P(all 5 defective) = P(defective) x P(defective) x P(defective) x P(defective) x P(defective)

where P(defective) = 5/12 for each transistor.

Plugging in the values, we get:

P(all 5 defective) = (5/12) x (5/12) x (5/12) x (5/12) x (5/12) = 0.0024

b. The probability that none of the selected transistors are defective is 0.163 or 16.3%.

To calculate this probability, we use the complement rule:

P(none defective) = 1 - P(at least one defective)

To calculate P(at least one defective), we can use the complement rule again:

P(at least one defective) = 1 - P(none defective)

So, we need to find P(none defective) first:

P(none defective) = P(not defective) x P(not defective) x P(not defective) x P(not defective) x P(not defective)

where P(not defective) = 7/12 for each transistor.

Plugging in the values, we get:

P(none defective) = (7/12) x (7/12) x (7/12) x (7/12) x (7/12) = 0.163

Then, we can find P(at least one defective):

P(at least one defective) = 1 - P(none defective) = 1 - 0.163 = 0.837

Finally, we can find P(none are defective) using the complement rule:

P(none defective) = 1 - P(at least one defective) = 1 - 0.837 = 0.163.

The inequality graphed on the number line can be written as:

-3 ≤ x < 2

Here we can see an inequality graphed on a number line, we can see that we start with a closed circle at x = -3

A closed circle means that x = -3 is a solution.

And we can see that it ends with an open circle at x = 2, the open circle means that the point is not a solution.

Then the inequality thati is shown in the number line is written as:

The college student can spend $35 in December to achieve his goal of a mean spending of $60 per month for the remaining five months.

To find out how much the college student can spend in December, we need to consider the total amount he has already spent in the first four months and his goal of having a mean spending of $60 per month for the remaining five months.

Let's calculate the total amount spent in the first four months:

Total spent = $65 + $55 + $70 + $75 = $265

The student's goal is to spend a mean of $60 per month for the remaining five months. Since there are five months remaining, the total amount he plans to spend is:

Total planned spending = $60 * 5 = $300

To find out how much he can spend in December, we subtract the total spent in the first four months from the total planned spending:

Amount he can spend in December = Total planned spending - Total spent

= $300 - $265

= $35

Answer:

To find the effective annual rate (EAR) of an account that pays interest at the nominal rate of 7% per year, compounded daily, we can use the following formula:

EAR = (1 + r/n)^n - 1

where r is the nominal annual interest rate (expressed as a decimal), and n is the number of times the interest is compounded in a year.

For daily compounding, n = 365 (since there are 365 days in a year), so we have:

EAR = (1 + 0.07/365)^365 - 1 = 0.0725 or 7.25%

To find the effective annual rate for hourly compounding, we need to adjust the value of n to account for the fact that interest is compounded more frequently. There are 365 days * 24 hours = 8,760 hours in a year, so we can use n = 8,760:

EAR = (1 + 0.07/8760)^8760 - 1 ≈ 0.0727 or 7.27%

Therefore, the effective annual rate for hourly compounding is approximately 7.27%.

Parker would have approximately $13,774 in his account when Matthew's money has tripled in value.

We have,

For Matthew's investment, the continuous compounding formula can be used:

\(A = P \times e^{rt}\)

Where:

A = Final amount

P = Principal amount (initial investment)

e = Euler's number (approximately 2.71828)

r = Annual interest rate (in decimal form)

t = Time (in years)

In this case,

Matthew's money has tripled,

So A = 3P.

For Parker's investment, the formula for compound interest compounded annually is used:

\(A = P \times (1 + r)^t\)

Where:

A = Final amount

P = Principal amount (initial investment)

r = Annual interest rate (in decimal form)

t = Time (in years)

We need to find t when Matthew's money has tripled in value.

Let's set up the equation:

\(3P = P \times e^{rt}\)

Dividing both sides by P, we get:

\(3 = e^{rt}\)

Taking the natural logarithm of both sides:

ln(3) = rt

Now we can solve for t

t = ln(3) / r

For Matthew's investment,

r = 3 1/8% = 3.125% = 0.03125 (as a decimal).

For Parker's investment,

r = 2 3/4% = 2.75% = 0.0275 (as a decimal).

Now we can calculate t for Matthew's investment:

t = ln(3) / 0.03125

Using a calculator, we find t ≈ 22.313 years.

Now, we can calculate how much money Parker would have in his account at that time:

\(A = P \times (1 + r)^t\)

\(A = $8,000 \times (1 + 0.0275)^{22.313}\)

Using a calculator, we find A ≈ $13,774.

Therefore,

Parker would have approximately $13,774 in his account when Matthew's money has tripled in value.
