You can put this solution on YOUR website! Heights of men on a baseball team have a bell shaped distribution with a mean of 168 cm and a standard deviation of 5 cm. Using the empirical rule, what is the approximate percentage of the men between the following values?
a. 153 cm and 183 cm
(153-168)/5 = -3
(183-168)/5 = 3
---
Using Chybyshev, at least (1-(1/3)^2) = 0.8888.. = 89% of the data
lies between 153 and 183
================================
b. 158 cm and 178 cm
(158-168)/5 = -2
(178-168)/5 = +2
---
Using Chybyshev, at leas (1-(1/2)^2) = 0.75 = 75% of the data
lies between 158 and 178
=============================
