Question 1054768: Assume that​ women's heights are normally distributed with a mean given by mu equals 62.6 in​, and a standard deviation given by sigma equals 2.6 in.
​(a) If 1 woman is randomly selected, find the probability that her height is less than 63 in.
​(b) If 48 women are randomly selected, find the probability that they have a mean height less than 63 in.

a. z+=blue+%2863+-+62.6%29%2Fblue%282.6%29
compute z and then Find P(x <63) = P(z < z-value found)

b. z+=blue+%2863+-+62.6%29%2Fblue%282.6%2Fsqrt%2848%29%29
compute z and then Find P(x̄ <63) = P(z < z-value found)
