The height of adult women in the U.S. is normally distributed, with a mean height of 64 inches and a standard deviation of 3 inches. With this in mind, answer the following:
a) The shortest 10% of women are shorter than what height?
b) The middle 75% of all women are between what two heights?
c) The tallest 5% of women are taller than what height?
I'm so confused. Please help.
Try using this website for making calculations that require the normal distribution function.
For part a), I get
For art (c), I get 68.94 inches
I had to guess the limits and see what the fractions fell within those limits, using the computation tool provided. Some iteration was required.
