Anita is filling a pool with water. Currently, there are 60 gallons of water in the pool, and she is filling the pool at a rate of 50 gallons every 5 minutes. She wants to fill the pool with at least 200 gallons of water. Enter an inequality that represents all possible values for the number of minutes (m) that it will take to fill the pool. $$

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.
