a-State the decision rule
b-compute the pooled estimate of the population varaince
c-compute the test statistic
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?
Ho:u1=u2
H1:u1/=u2
