Question

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:


b. Determine the test statistic (round to 3 decimal places): __________________

c. Determine the p-value (round to 3 decimal places):

d. Result (Circle one & justify): REJECT ???? FAIL TO REJECT ????

Reason:


e. State a conclusion within the context of the scenario:

Answer 1

Do your question marks represent  sample size; mean; stan. dev.?

 

if μ₁ μ₂ represent the populations means how would you write the hypotheses?
