In a game, a player starts with 100 points. Each question has two parts and an incorrect answer for both parts results in a loss of 1 point. The student loses one-half of a point for getting only one part of the question correct. At the end of a 25 question round, the player has 82.5 points. What TWO equations and solutions represent x missed points? Answer choices:
A. 100−x=82.5
The player misses 17.5 points.

B. 82.5−x=100
The player misses 17.5 points.

C. 82.5−x=100
The player misses 18.5 points.

D. x−100=−82.5
The player gets 7.5 points.

E. x−100=−82.5
The player gets 8.5 points.

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.
