c-Compute the test statistic

d-State your decision about the null hypothesis

e-Estimate the p-value

A random sample of 10 observations from one population revealed a sample mean of 23 and a sample deviation of 4. A random sample of 8 observations from another population revealed a sample mean of 26 and a sample standard deviation of 5. At the .05 significance level, is ther a differnece between the population means?
