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.
