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.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
