The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 250.8 and a standard deviation of 65.7. (All units are 1000 cells/uL.)Using the empirical rule, find each approximate percentage below.a. What is the approximate percentage of women with platelet counts within 3 standard deviations of the mean, or between 53.7 and 447.9?b. What is the approximate percentage of women with platelet counts between 185.1 and 316.5?.....a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 53.7 and 447.9.(Type an integer or a decimal. Do not round.)

Suppose baby kittens' weights are normally distributed with a mean of 11.4 and a standard deviation of 2.1. The Z-score tells you how many units above the average (if Z-score is positive) or below the average (if Z- Score is negative) any particular baby kitten's weight is. Find the baby kitten weight that corresponds to the following Z-scores. Use the formula Z where u is the mean, o is the standard deviation, and X is the baby kitten weight. a. Z = = 0.07, X = b. Z = 1.63, X =
