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 148 lb. Assume that the standard deviation of the weights of all 15-year old boys in the city is known to be 16.1 lb. Use the traditional method of testing hypotheses.
149 141 160 151 134 189 157 144 175 127 164
Choose the correct conclusion associated with this experiment.
I am pretty sure it is either B or C but I am torn on which one to choose so that is why I am only going to include two answer choices...
Edit: I think I figured it out on my own, I am going to go with B, I am pretty sure that is the correct answer
B) 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 148 lb.
C) Do not reject H0; At the 1% significance level there is sufficient evidence to warrant rejection of the claim that these sample weights come from a population with a mean greater than 148 lb.
