The mean of a distribution of scores is 49, with a standard deviation of 16. Calculate the standard error for a distribution of means based on samples of 30 people.

Answers

Answer 1

the standard error for a distribution is 33

Answer 2

The standard error for distribution is 33. Therefore the correct response is 33.

What is Standard Deviation?

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.

The lowercase Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation. Standard deviation may be written as SD.

The standard error of a statistic (such as the sample mean) and the standard deviation of a population or sample are fundamentally separate but related concepts. The standard deviation of the set of means that would be discovered by taking an unlimited number of repeated samples from the population and calculating a mean for each sample is the sample means standard error.

What are the limits of economic science?

Explanation:

The primary limitation of economics, Chetty argues, is that economists have a limited ability to run controlled experiments for theoretical macroeconomic conclusions. The high monetary cost and ethical standards make these types of controlled experiments impractical.

Economics is a social science that examines how people produce, distribute, and consume goods and services. This means that much of the field is based on human behavior, which can be somewhat irrational and unpredictable.

A random sample of 100 units is drawn a production process every

half hour. The fraction of nonconforming product manufactured is

0.03. What is the probability that ˆp ≤ 0.04 if the fraction

nonconforming really is 0.03?

Answers

The probability that ˆp ≤ 0.04 if the fraction nonconforming really is 0.03 is written below.

What is a fraction?

A number that represents a rational number is called a common fraction.

X=0,1,2,3,…..; q=1-p

The probability that (p∧ ≤ 0.06) , substitute the values of sample units (n), and the probability of nonconformities (p) in the probability mass function of the binomial distribution.

Consider x   to be the number of non-conformities. It follows a binomial distribution, with n   being 50 and p  being 0.03. That is,

binomial (50,0.02)

Also, the estimate of the true probability is,

p∧  = x/50

The probability mass function for binomial distribution is,

Where,

X=0,1,2,3,…..; q=1-p

The calculation is obtained as

P(p^ ≤ 0.06) = p(x/20 ≤ 0.06)

        = 50cx ₓ (0.03)x ₓ (1-0.03)50-x  

=    (50c0 ₓ (0.03)0 ₓ (1-0.03)50-0 + 50c1(0.03)1 ₓ (1-0.03)50-1 + 50c2 ₓ (0.03)2 ₓ (1-0.03)50-2 +50c3 ₓ      (0.03)3 ₓ (1- 0.03)50-3 )

=(  ₓ (0.03)0 ₓ (1-0.03)50-0 +  ₓ (0.03)1 ₓ (1-0.03)50-1 +   ₓ (0.03)2 ₓ (1-0.03)50-2   ₓ (0.03)3 ₓ (1-0.03)50-3 )

Which word describes the amount of matter an object contains? altitude density mass pressure

Answer:

Mass is the correct answer.

Explanation:

As mass is defined as the amount of matter contained in the substances or an object.

so, the answer is mass.

Hope it helps...

Mass describes the amount of matter an object contains. Thus, option C is correct.

What is the matter?

Matter is everything with mass that takes up space. Atoms are the minuscule constituent parts of matter. Matter exists in three different states.

The amount of matter in a thing is measured by its mass. The object in question is going to have the exact same mass whatever its location is in the vastness of the cosmos. Contrarily, weight is a measurement of the amount of gravitational pull being applied to an object.

The term "matter" refers to anything with mass and spatial remit. The measure of space it occupies is its volume. Although millilitres, ounces, and occasionally quarts are also frequently employed for determining liquid volume, litres are the most common unit. Therefore, option C is correct.

If the word buccaneer were added to this dictionary,

Without understanding the exact content, context or scope of the dictionary that you're talking about, it is challenging to determine the exact position of the word "buccaneer." However, using simple logic, as per the alphabetical order, the word "buccaneer" can likely be positioned between the words based on the order of their starting alphabets.

For example, if the words "bubble" and "bucket" are already present in that particular dictionary, the word "buccaneer" can be placed between them, and it would follow "bubble" and precede "bucket".

The precise positioning of "buccaneer" would rely on the words that are already there in the dictionary and the sorting rules used by the publisher which can include (and not be limited to)- the consideration of spaces, special characters, capitalization, etc.

Answers

[D] The biggest problems for the environment are caused by humans.

The author's perspective in "Human Impact on our Environment" can be identified as D) The biggest problems for the environment are caused by humans.

This perspective implies that human activities have a significant and detrimental effect on the environment.

It suggests that humans, through their actions and behaviors, are the primary cause of environmental issues and challenges we face today.

The author likely believes that factors such as pollution, deforestation, habitat destruction, overconsumption, and climate change are predominantly driven by human actions.

This perspective aligns with scientific consensus and extensive research on the topic.

Numerous studies have shown that human activities, particularly industrialization and unsustainable practices, have led to a range of environmental problems.

These problems include air and water pollution, loss of biodiversity, habitat degradation, and climate change.

By emphasizing the impact of human actions on the environment, the author likely aims to raise awareness and promote a sense of responsibility for addressing these issues.

It suggests that changes in human behavior, policy interventions, and sustainable practices are necessary to mitigate and reverse the negative effects on the environment.

A system of organizations, people, activities, information, and resources involved in supplying a product or service to a consumer is called a supply chain.

A supply chain encompasses the entire process of delivering a product or service to a consumer, involving various interconnected components. Let's break down the elements of a supply chain:

Organizations: It involves multiple organizations, such as suppliers, manufacturers, distributors, wholesalers, retailers, and even service providers. These entities collaborate and interact to ensure the smooth flow of products or services.People: Individuals within each organization play crucial roles in the supply chain. They include managers, employees, logistics personnel, sales representatives, and other stakeholders involved in various activities throughout the chain.Activities: The supply chain encompasses a range of activities, including procurement, production, inventory management, transportation, warehousing, order fulfillment, and customer service. Each activity contributes to the overall process of delivering the product or service to the consumer.Information: Information flows throughout the supply chain, enabling coordination, decision-making, and synchronization. It includes data on inventory levels, customer orders, production schedules, logistics tracking, and demand forecasts.Resources: Various resources are required in a supply chain, such as raw materials, equipment, facilities, transportation vehicles, and financial capital. Effective resource management is crucial for optimizing the supply chain's performance.

In summary, a supply chain integrates organizations, people, activities, information, and resources to ensure the efficient and effective delivery of products or services from suppliers to consumers.
