P-value & confidence interval

Identify The test statistic, t (rounded to two decimal places), The P-value (rounded to three decimal places), Construct a confidence interval suitable for testing the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. (<h1-h2<) A study was done on proctored and nonproctored tests. The results are ProctoredNonproctored shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both x parts. H2 35 31 77.71 82.71 10.65 19.72 H: H > H2 H:HH2 OC. Ho: H1 H2 'D. Ho: H1 H2 H: H1 <H2 H: H <H2 The test statistic, t, is (Round to two decimal places as needed.)
