G Question: Are men who get married entering their first marriage older than they did 30 years ago? Thirty years ago, the age at first marriage for men was about 24 years old. Which of the following would be the best choice of hypotheses to answer the age at first marriage question? a) H0: LaTeX: \mu=24μ = 24 and Ha: LaTeX: \mu<24μ < 24 b) H0: LaTeX: \mu=24μ = 24 and Ha: LaTeX: \mu\ne24μ ≠ 24 c) H0: LaTeX: \mu=24μ = 24 and Ha: LaTeX: \mu>24μ > 24 d) H0: LaTeX: \mu<24μ < 24 and Ha: LaTeX: \mu=24μ = 24 e) H0: LaTeX: \mu\ne24μ ≠ 24 and Ha: LaTeX: \mu=24μ = 24 f) H0: LaTeX: \mu>24μ > 24 and Ha: LaTeX: \mu=24

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
