6.20 z-score for given probability in tails For a normalTRY distribution,a. Find the z-score for which a total probability of 0.02 fallsmore than z standard deviations (in either direction)from the mean, that is, below pZo or above + zo.b. For this z, explain why the probability more than zstandard deviations above the mean equals 0.01.c. Explain why +2.330 is the 99th percentile.
