To test the following hypotheses

12.14      a. To test the following hypotheses, a statistics practitioner randomly sampled 100 observations and found x = 106 and s = 35. Calculate the test statistic (and for Excel users, the p-value) of a test to determine whether there is enough evidence at the 1% significance level to infer that the alternative hypothesis is true.

 

H0:   m  = 100

H1:   m 7 100

b.     Repeat part (a) with s = 25.

c.     Repeat part (a) with s = 15.

d.    Discuss what happens to the t-statistic (and for Excel users, the p-value) when the standard devi- ation decreases.
