We wish to see if the dial indicating the oven temperature for a certain model of oven is properly calibrated. four ovens of this model are selected at random. the dial on each oven is set to 300∘f and, after one hour, the actual temperature of each is measured. the temperatures measured are 305∘f, 310∘f, 300∘f, and 305∘f. assuming that the actual temperatures for this model, when the dial is set for 300∘f, are normally distributed with mean , we test whether the dial is properly calibrated by testing the hypotheses : = versus : ≠ . based on the data, the ‑value for this test is: between 0.1 and 0.05. between 0.05 and 0.025. between 0.025 and 0.01.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
