PROBLEM 11E

For a female freshman in a health fitness program, let X equal her percentage of body fat at the beginning of the program and Y equal the change in her percentage of body fat measured at the end of the program. Assume that X and Y have a bivariate normal distribution with μX = 24.5, σ2X= 4.82 = 23.04, μY = −0.2,σ2Y = 3.02 = 9.0, and ρ = −0.32. Find

(a) P(1.3 ≤ Y ≤ 5.8).

(b) μ Y|x, the conditional mean of Y, given that X = x.

(c) σ 2 Y|x, the conditional variance of Y, given that X = x.

(d) P(1.3 ≤ Y ≤ 5.8 |X = 18).

The answer to “For a female freshman in a health fitness program, let X equal her percentage of body fat at the beginning of the program and Y equal the change in her percentage of body fat measured at the end of the program. Assume that X and Y have a bivariate normal distribution with ?X = 24.5, ?2X= 4.82 = 23.04, ?Y = ?0.2,?2Y = 3.02 = 9.0, and ? = ?0.32. Find(a) P(1.3 ? Y ? 5.8).(b) ? Y|x, the conditional mean of Y, given that X = x.(c) ? 2 Y|x, the conditional variance of Y, given that X = x.(d) P(1.3 ? Y ? 5.8 |X = 18).” is broken down into a number of easy to follow steps, and 109 words.
