Kellie is given the following information:
if two lines are perpendicular, then they intersect at a right angle. lines a and b are perpendicular.
she concludes that lines a and b intersect at a right angle. which statements are true? check all that apply.
she used inductive reasoning.
she used the law of detachment.
her conclusion is valid.
the statements can be represented as "if p, then q and if q, then r."
her conclusion is true.

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.
