A random sample of 15 observations from the first population revealed a sample mean of 350 and a sample standard deviation of 12

A random sample of 15 observations from the first population revealed a sample mean of 350 and a sample standard deviation of 12. A random sample of 17 observations from the second population revealed a sample mean of 342 and a sample standard deviation of 15. At the 0.10 significance level, is there a difference in the population means?

The null and alternate hypotheses are:
H0: µ1 = µ2
H1: µ1 ≠ µ2

(a) state the decision rule, (b) compute the pooled estimate of the population variance, (c) compute the test statistic, (d) state your decision about the null hypothesis, and (e) estimate the p-value.
