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. 146 140 160 151 134 189 157 144 175 127 164 What is the test statistic? z=[test] (round to 2 decimal places) What is the p-value? p=[p] What are the critical values? z=+/- [critical] (round to 3 decimal places) What is your conclusion about the claim? [conclusion] s = support the claim r = reject the claim f = fail to reject the claim n = not enough evidence to support the claim
