Assume that an adult female is randomly selected. Suppose

females have pulse rates that are normally distributed with a mean

of

74.074.0

beats per minute and a standard deviation of

11.511.5

beats per minute. Find

Upper P 90P90 ,

which is the pulse rate separating the bottom

9090 %

from the top

1010 %.
