The heights of women aged 30 to 35 are approximately normal with mean 63 inches and standard deviation 2.4 inches. men the same age have mean height 70 inches with standard deviation 2.5 inches. if one woman and one man are randomly selected, what is the probability that heights of both are greater than 66 inches tall? assume that heights of women and men are independent.

Answer

given,

mean of women  (μ)=63 inches

standard deviation of women (σ)= 2.4 inches

mean of men (μ)=70 inches

standard deviation of women (σ)= 2.5 inches

for women

using z-table

using z-table

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
