It is reported that the cholesterol level for U. S. women ages between 50 and 59 yields a mean
228 milligrams per deciliter and a standard deviation 43.8 milligrams per deciliter. (Assume the
distribution is Normally Distributed). 1. If 200 U. S. women in the 50-59 age group were
randomly selected, about how many would you expect to have a total cholesterol level greater
than 200 milligrams per deciliter of blood? Please show your work. Thank you.
Solution
Here level of cholestrol follows normal(228,43.8)...Hence 200*P(X greater than
200) would give me the answer 200(1-0.26037107)=147.2586...Hence approximately 148
peoples weight would be greater than 200...Please rate..Thanx
