The distance in feet that Karina swims in a race is represented by 6d - 6, where d is the distance for each lap. What is an expression equivalent to 6d - 6?
Choose the correct answer below.
OA. 6d - 6 = -6 + 6d
OB. 60 - 6 = -6(d + 6)
OC. 6d - 6 = 6-6d
OD. 6d - 6 = 6(d-6)

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.
