The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes with a sample standard deviation of 0.5 minutes. We want to determine whether or, not the mean waiting time of all customers is significantly different than 3 minutes. Then the correct set of hypotheses is Select one: O a. HO: u 3 H1: u = 3.1 O b. HO: µ = 3 H1: µ # 3 O c. HO: µ + 3 H1: µ = 3 d. H0: μ- 3.1 H1: u # 3

The mean weight of a fire ant worker is 3.11 mg with a standard deviation of .49 mg. Suppose we randomly select 14 different fire ant workers having weights F1, F2, , F14. Let S = F1 + F2 + ...+F14 and let M = S/14. This means S is the sample sum and M is the sample mean of the selected ant weights. (Note: random selection means F1 F14 are independent.). Assume the Fis are normally distributed. j) What is the expected value of M - 3.11 ? k) What is the standard deviation of [(M - 3.11)/49]/srt14
