Answer #1

The hypothesis being tested is:

H0: µ1 = µ2 = µ3

Ha: Not all means are equal

Mean n Std. Dev
4.2 50 1.13 How well is it to study/work no
3.3 50 0.81 How have your grades been impac
4.2 50 1.00 How has your productivity been
3.9 150 1.08 Total
ANOVA table
Source SS    df MS F    p-value
Treatment 28.37 2 14.187 14.49 1.80E-06
Error 143.92 147 0.979
Total 172.29 149

The p-value is 0.0000.

Since the p-value (0.0000) is less than the significance level (0.05), we can reject the null hypothesis.

Therefore, we can conclude that not all means are equal.
