Neee asa is training for a race that is 10 kilometers long. on saturday he ran 2.5 km. he plans to add 0.5 km to his distance every saturday. hector's calculations: 2.5 + 0.5 = 3.0 6.5 + 0.5 = 7.0 3.0 + 0.5 = 3.5 7.0 + 0.5 = 7.5 3.5 + 0.5 = 4.0 7.5 + 0.5 = 8.0 4.0 + 0.5 = 4.5 8.0 + 0.5 = 8.5 4.5 + 0.5 = 5.0 8.5 + 0.5 = 9.0 5.0 + 0.5 = 6.0 9.0 + 0.5 = 9.5 6.0 + 0.5 = 6.5 9.5 + 0.5 = 10.0 the equation equivalent to hector’s calculations is 2.5 + 0.5x = 10. use either of these methods to determine how many weeks it will take hector to reach his goal of a 10 kilometer run.

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.
