Suppose you use the weights 7, 1, 7, 1, 7, 1, 7, 1, 7, 1, 7, 1} instead of {3, 1, 3, 1, 3, 1,3, 1, 3, 1, 3, 1} in the UPC method. Do you think this altered method will detect single- digit errors? Either give several examples of numbers with an error that will not be
detected or explain why you think all such single-digit errors will be detected.

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
