In a study of proctored and non-proctored tests in an online course, researches obtained the data below:
Group 1 (Proctored): ?? = 30, ??¯ = 74.30, ?? = 12.87 Group 2 (Non-proctored): ?? = 32, ??¯ = 80.62, ?? = 22.09
Use of 0.05 significance level to test the claim that students taking non-proctored tests get a higher mean than those taking proctored tests (use the p-value method).
a. Give the symbolic null & alternative hypotheses. Use correct notation.
H0: HA:
