Please help Ken predicts that the average temperature will be −5°C in December. If he predicts the temperature will rise 6°C in January and fall 3°C in February, which of the following equations can he use to find the sum of the temperatures for those months? CHECK ALL THAT APPLY!

A. [6 + 3] + 5 = 14

B. (–5) + [3 + 6] = –4

C. [(–5) + (–3)] + 6 = –2

D. 5 + [(–6) + (–3)] = –4

E. [6 + (–5)] + (–3) = –2

F. [(–5) + 6 ] + (–3) = 4

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
