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 Miami University administered CARS to 172 business students. One of the objectives of the study was to determine whether there is a difference in the level of computer anxiety experienced by female and male business students (with known variances). They found the following: X_bar(male)=40.26, variance_male=169, n_male=100; X_bar (female)=36.85, variance_female=81, n_female=72. At the 0.05 level of significance, is there evidence of a difference in the mean computer anxiety experienced by female and male business students? Select one: a. Z_stat=2.03 and Hypothesis of no difference is rejected b. Z_stat=2.03 and Hypothesis of no difference is not rejected c. Z_stat=1.89 and Hypothesis of no difference is not rejected d. Z_stat=1.89 and Hypothesis of no difference is rejected
