Question 1179247: Assume that women's weights are normally distributed with a mean given by 𝜇=143 lb and a standard deviation given by 𝜎=29 lb.
a)If 91 women are randomly selected, find the probability that they have a mean weight above 175.

Hi
Distribution: normal with µ = 143 and σ = 29
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
n = 91
P( x > 175) = normalcdf(175,9999,143,29/√91) = basically zero % probability

Wish You the Best in your Studies.
