Compute the value of the test statistic. Note: Round your answer to 3 decimal places. What is the p- value? What is your decision regarding HO? The null and alternate hypotheses are: = Ho: H1 H2 H1: H1 H2 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 16 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?
