Question

Consider the following hypothesis test :

H0:μ =12.5

Ha:μ ‡12.5

**THAT A sample of size 18 provided a sample mean (12.9) and sample  standard deviation is (0.8).

a-Compute the test statistic.

b-Determine the range of p-value from the table of t-distribution? What is the  rejection rule ?

and what is your conclusion at α=0.01?

c-What is the rejection rule ,using critical vale approach? What is your conclusion at   α=0.05?
