Question

Using the accompanying table of​ data, blood platelet counts of women have a​ bell-shaped distribution with a mean of 255.1 and a standard deviation of 65.3. ​(All units are 1000 ​cells/mu​L.) Using​ Chebyshev's theorem, what is known about the percentage of women with platelet counts that are within 2 standard deviations of the​ mean? What are the minimum and maximum possible platelet counts that are within 2 standard deviations of the​ mean?

Answer 1
