Careena likes throwing rocks at the ocean. When she throws the rock upward from 160 ft above the ocean, h(t) = - 16t2

+ 48t + 160 models the height, h, of the rock above the

ocean as a function of time, t, in seconds. How long will it take the rock to reach the

ocean (h = 0)​

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
