Heights of men on a baseball team have a bell-shaped distribution with a mean of 174 cm and a standard deviation of 6 cm
.
Using the empirical rule, what is the approximate percentage of the men between the following values?
a. 162 cm and 186cm
(162-174)/6 = -12/6 = -2 ; (186-174)/6 = 12/6 = 2
Ans:: The empirical Rule states that 95% of the data values are
within 2 standard deviations of the mean.
----------------------------------
b. 168cm and 180cm
(168-174)/6 = -6/6 = -1 ; (180-174)/6 = 1
Ans:: The emperical Rule states that 68% of the data values are
within 1 standard deviation of the mean.
