Question 1182335: The mean height of women in a country (ages 20-29) is 64.3 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 σ=2.75
The probability that the mean height for the sample is greater than inches is_____?
(Round to four decimal places as needed.) Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! z=(x bar-mean)/sigma/sqrt(n)
>(65-64.3)/2.75/sqrt(70)
>0.7*sqrt(70)/2.75
>2.130
probability is 0.0166
