Question 1173135: The mean height of women in a country (ages 20-29) is 64.2 inches. A random sample of 70 women in this age group is selected. What is the probability that the mean height for the sample is greater than 65 inches? Assume o=2.98.
The probability that the mean height for the sample is greater than 65 inches is ? Answer by ewatrrr(24785) (Show Source):
Hi,
The mean height of women in a country (ages 20-29) is 64.2 inches
m = 64.2 and o=2.98.
Using Calculator
P( x̄ > 65) = 1 - P(x ≤ 65) = 1 - normalcdf(-9999,65,64.2,2.98)
P(x̄ > 65) = 1 - .6058 = .3942
