Luis created the graph below to show the temperature from 8:00 a. m. (8 hours after midnight) until 8:00 p. m.
On this graph, 4:00 p. m. occurs at 16 hours after midnight, and 6:00 p. m. occurs at 18 hours after midnight. Which statements are true about the temperatures Luis recorded on the graph? Select THREE answers.
The temperature increased until 4:00 p. m.
The temperature was not recorded between 4:00 p. m. and 6:00 p. m.
The temperature decreased after 6:00 p. m.
The temperature increased and then decreased before holding constant.
The temperature increased more quickly between 12:00 p. m. and 4:00 p. m. than before 12:00 p. m.

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.
