The Computer Anxiety Rating Scale (CARS) measures an individual's level of computer anxiety, on a scale from 20 (no anxiety) to 100 (highest level of anxiety). Researchers at a large university administered CARS to 80 business students. One of the objectives of the study was to determine whether there is a difference between the level of computer anxiety experienced by female students and male students.

Of the 80 student survey takers, 40 were male, 40 were female. The results are in the table below for statistical analysis of variability between the two samples. All of these analyses are run with a 95% level of confidence.

Males

Females

Sample Mean

40.26

36.85

Sample Standard Deviation

13.35

9.42

Perform the test chosen in part (d) of the previous problem and supply this information:

a. What is the value of the test statistic?

b. Find the probability of getting these results if there is no difference in anxiety ratings between the two genders.

c. What is your conclusion, is there evidence of a difference in computer anxiety experienced by males and females?

Thanks for any help!
