Which of the formulae is false?
(a) \overline{}{z_{1}z_{2}}= \bar{z_{}1} \bar{z_{}2}
(b) arg\bar{z} = arg\bar{z}
(c) |\bar{z}| = |z|
(d) \overline{z_{1}+z_{2}}=\bar{z_{1}}+ \bar{z_{2}}
(e) \overline{z_{1}\bar{z}_{2}}=\bar{z_ {1}}z_{2} forz_{2}\neq 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
