Which statements are true when verifying the solution set of StartAbsoluteValue 6 minus StartFraction x Over 3 EndFraction EndAbsoluteValue greater-than 18 as x less-than negative 36 or x greater-than 72? Check all that apply. Substituting 80 for x into the original inequality will create a false statement. Substituting 50 for x into the original inequality will create a false statement. Substituting 100 for x into the original inequality will create a true statement. Substituting –36 for x into the original inequality will create a false statement. Substituting 0 for x into the original inequality will create a true statement. Substituting –50 for x into the original inequality will create a true statement.

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.
