ivann1987 [24]2 years ago
4 0

The number of six samples that could belong to the same population is equivalent to six.

Option A is the correct answer.

<h3>What is the standard deviation?</h3>

The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.  

The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.

Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.

This is the description about Delia's character in the story by Edith Wharton:

Although I was no able to find the passage, there are some characteristics about Delia Benson Corbett that can be useful to analyze her choices and actions.

Delia was challenged mentally and emotionally by her first husband. However, she was able to leave her past behind. She uses her irony to deal with her past suffering and she also grew strength by focusing on her own and her job, as well as her belief in religion.

<h3>What is an essay?</h3>

In this exercise, you have to write the description about the passage using an essay structure.

An essay is a written text that can express an opinion about something. You need to do a research before writing an essay so you can get all the information to justify your opinions. In this case, you have to analyze the passage given.

To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians
yKpoI14uk [10]

The standard error of the difference of sample means is 0.444

From the complete question, we have the following parameters

<u>Canadians</u>

  • Sample size = 50
  • Mean = 4.6
  • Standard deviation = 2.9

<u>Americans</u>

  • Sample size = 60
  • Mean = 5.2
  • Standard deviation = 1.3

The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.

This is represented as:

SE = \frac{\sigma}{\sqrt n}

The standard error of the Canadian sample is:

SE_1 = \frac{2.9}{\sqrt{50}}

So, we have:

SE_1 = 0.41

The standard error of the American sample is:

SE_2 = \frac{1.3}{\sqrt{60}}

So, we have:

SE_2 = 0.17

The standard error of the difference of sample means is then calculated as:

SE= \sqrt{SE_1^2 + SE_2^2}

This gives

SE= \sqrt{0.41^2 + 0.17^2}

SE= \sqrt{0.197}

Take square roots

SE= 0.444

Hence, the standard error of the difference of sample means is 0.444
