. Complete the following hypothesis test given a

sample with n = 110 and x-bar = 98.7.

null hypothesis Ho:u = 98.6

alternate hypothesis Ha:u > 98.6 (greater than, right or one-tail test)

1. test statistic TS: z calc = __________

1. rejection region RR: p = __________ (use Table B to find the p value)

1. conclusion CC: _______________ (reject Ho or support Ho)

use an alpha of 0.05.

7. Refer to Example 14.10 in the textbook. Perform a hypothesis test for Ho:u = 98.6 using

a confidence interval. Find the 95% CI for an x-bar = 98.5 and n = 60.

1. 95% CI = [ __________ , __________ ]

1. 98.6 falls __________ the confidence interval. (inside or outside)

1. Therefore, we __________ Ho:u=98.6. (reject or support)
