Explanation:
To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians and americans. The canadians spend an average of hours a week commuting, with a standard deviation hours. The mean and standard deviation for the sample of americans is hours and hours, respectively. The standard error of the difference of sample means is:.
The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
Canadians
Sample size = 50Mean = 4.6Standard deviation = 2.9Americans
Sample size = 60Mean = 5.2Standard deviation = 1.3The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:
[tex]SE = \frac{\sigma}{\sqrt n}[/tex]
The standard error of the Canadian sample is:
[tex]SE_1 = \frac{2.9}{\sqrt{50}}[/tex]
So, we have:
[tex]SE_1 = 0.41[/tex]
The standard error of the American sample is:
[tex]SE_2 = \frac{1.3}{\sqrt{60}}[/tex]
So, we have:
[tex]SE_2 = 0.17[/tex]
The standard error of the difference of sample means is then calculated as:
[tex]SE= \sqrt{SE_1^2 + SE_2^2}[/tex]
This gives
[tex]SE= \sqrt{0.41^2 + 0.17^2}[/tex]
[tex]SE= \sqrt{0.197}[/tex]
Take square roots
[tex]SE= 0.444[/tex]
Hence, the standard error of the difference of sample means is 0.444
