A middle school football player, Bo, is just learning how to kick field goals. Currently, he only makes of his kicks.
A number cube is being used to simulate the result of Bo's kicks where the numbers 1 or 2 represent a made field

number cube to answer each question.

Ineed to know the answer to this algebra question.

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.
