Maria is to select one number from the set {60,61,62,63,64,65,66,67,68,69} at random. consider the following three events. event x: the selected number is an even number. event y: the selected number is a multiple of 3. event z: the selected number is a multiple of 5. part a: list the outcomes that are in event x or in event y but not in both events. part b: list the outcomes that are in both events x and y but not in z.

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
