To test the null hypothesis that the mean waist size for males under 40 years equals 34 inches versus the hypothesis that the mean differs from 34, the following data were collected:33,33,30,34,40,35,35,32,32,34,36,30
1) calculate that sample mean and sample standard deviation?
2) calculate the T-value of the test statistic ?
3) find the p-value?
4) Test the stated hypothesis at a=.05 and write conclusion
