QUESTION:

A simple random sample of 15-year old boys from one city is obtained and their weights
(in pounds) are listed below. Use a 0.01 significance level to test the claim that these sample weights come from a population with a mean equal to 147 lb. Assume that the standard deviation of the weights of all 15-year old boys in the city is known to be 16.7 lb. Use the traditional method of testing hypotheses.

146 140 160 151 134 189 157 144 175 127 164.
-------------------
ANSWERS:
H0: µ = 147 lb
H1: µ J 147 lb
Test statistic: z = 1.26
Critical-values: z = ± 2.575
Do not reject H0; At the 1% significance level, there is not sufficient evidence to warrant rejection of the claim that these
sample weights come from a population with a mean equal to 147 lb.
