A simple rаndоm sаmple оf 15-yeаr оld 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.  Your scratch paper must show all five steps as demonstrated in the videos or you will not receive credit.             146   140    160    151    134    189    157    144    175    127    164            What is the test statistic? z=[test] (round to 2 decimal places) 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
