Answer #1

Given,

Null hypothesis : Ho : ; Difference in the average number of facebook friends between men and women is zero

Alternate Hypothesis : H1 : Difference in the average number of facebook friends between men and women is not zero

Assumed :0.05

As p-value : 0.2577 is greater than : 0.05 ; Fail to reject null hypothesis.

There is not sufficient evidence to conclude that the Difference in average number of facebook friends between men and women is not zero

For that matter even if =0.01 also,

As p-value : 0.2577 is greater than : 0.01 ; Fail to reject null hypothesis.

There is not sufficient evidence to conclude that the Difference in average number of facebook friends between men and women is not zero

For this assignment, use data from W1 Midweek Assignment. Using Minitab Express, compute a one-sample t-test comparing the age of your sample to the age of the general population of college students in traditional on-ground universities. Assume the population mean is 21. Move your output into a Microsoft Word document and write a 1-paragraph, APA-formatted interpretation of the results.
