Hi! I need to know the test statistic, along with the. P-value, followed by the test conclusions.

A study was done on proctored and nonproctored tests. The results are shown in the table. Assume that the two samples are independent Proctored Nonproctored simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are H2 equal. Complete parts (a) and (b) below. n 31 32 X 74.79 81.83 S 10.27 20.52 a. Use a 0.05 significance level to test the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. What are the null and alternative hypotheses? A. HO: H1 = H2 OB. HO: M1 # H2 H1: H1 H2 H1: M1 # H2 The test statistic, t, is . (Round to two decimal places as needed.)
