What is the domain of the function represented by these ordered pairs ? {(-2,1), (0,0), (3,-1), (-1,7), (5,7)} {-2,-1,0,3,5} {-1,0,1,7} {-2,-1,0,1,3,5,7} {0,1,2,3,5}

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
