Hypothesis testing problems

A sample of n=9 scores is obtained from a normal population distribution with o-=12. The sample mean is M=60.

a- with a two-tailed test and o=.05,use the sample data to test the hypothesis that the population mean is u=65.

b- with a two-tailed test and o=.05, use the ample data to test the hypothesis that the population mean is u=55.

c- In parts (a) and (b) of this problem, you should find the u=65 and the u=55 are both acceptable hypotheses. Explain how two different values can both be acceptable.

Solution Summary

Step by step method for testing the hypothesis under 5 step approach is discussed here.
