Assume The mean height of women in a counthry (ages 20-29) is 64 3 inches A random sample of 75 women in this age group is selected What is the probability that the mean height for the sample s greater than 65 nches The probablity that the mean height for the sample is greater than 65 inches is 00210 (Round to four decimal places as needed ) on the red indic ators to se ing All parts show

Explanation / Answer

solution:-

given mean = 64.3 ,standard deviation = 2.98

sample n = 75

we know that

z(65) =  (65-64.3)/[2.98/sqrt(75)]

= 2.03

P(x-bar > 65) = P(z > 2.03)

= 1P(Z<2.03)

= 10.9788

= 0.0212
