Homework answers / question archive / The null and alternate hypotheses are: H0:µ1= µ2 H1:µ1 ≠µ2 A random sample of 15 observations from the first population revealed a sample mean of 350 and a sample standard deviation of 12
The null and alternate hypotheses are:
H0:µ1= µ2
H1:µ1 ≠µ2
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 .10 significance level, is there a difference in the population means?
