3.2.41 Question Help The blood platelet counts of a group of women have a bol-shaped distribution with a mean of 2513 and a standard deviation of 64 5. (Al units are 1000 cells) Using the empirical rule, find each approximate percentage below a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 106.8 and 315.07 1. What is the approximate percentage of women with platelet counts between 57.3 and 144.8?

Answer 1

soluten 0 a) we Can write 186.8 as 251.3 - 64.5. Pe one standard deviation below the mean 251.3 +64.5 lie, one standard dentation above and 315.8 as the mean 68% of According to empirical Rule We know that data valuer valuer lies within standard deriation from the 7 so there will be approximately 68% of date with range 186.8 and 315.8 nean. " 3 b) we know that according to Empirical Role 99.7% of data les between standard deviation from the so there will be approximately 99.74. data within the 57.8 and uuus Stange of mean.
