Question 908315: glamorous magazine reported the average weight on an adult female in Europe is 154 pounds with a standard deviation of 31.5 points.
find the following: heavier than 185.5 pounds or P(X>185.5) =
lighter than 91 pounds P(X<91)

TI syntax is normalcdf(smaller, larger, �, σ).
P(X>185.5) = 1 - normalcdf(-9999, 185.5, 154, 31.5).
Note: The -9999 is used as the smaller value to be at least 5 standard deviations from the mean.
.....
P(X<91) = normalcdf(-9999, 91.00, 154, 31.5).
Since this is a continuous function, we have P(x < 91) = P(x ≤ 91)
