A distribution of measurements is relatively mound-shaped with a mean of 80 and a standard deviation of 14. Use this information to find the proportion of measurements in the given interval. Greater than 94
Homework Answers
Given,
= 80 , 
=
14
We convert this to standard normal as
P(X < x) = P(Z < x - / )
So,
P(X > 94) = P(Z > 94 - 80 / 14)
= P(Z > 1 )
= 1 - P(Z < 1)
= 1 - 0.8413
= 0.1587
