The relationship between body mass index (BMI) and systolic blood pressure in males 50 years of age is investigated. A random sample of n = 13 males is selected and their BMI and systolic blood pressures are measured. Let X be the body mass index (BMI) and Y the systolic blood pressure of males, 50 years of age. Given: The average and variance of the BMI is X = 26 and Var(X) = 15.026. The average and variance of the systolic blood pressure is Y = 126 and Var(Y) = 423. The covariance between X and Y is Cov(X,Y) = 69.87. For the estimated regression equation Y = Bo + B, X, it was found that B1 = 4.65.

A manufacturer has designed a process to produce pipes that are 10 feet long. The distribution of the pipe length, however, is actually Uniform on the interval 10 feet to 10.57 feet. Assume that the lengths of individual pipes produced by the process are independent. Let X and Y represent the lengths of two different pipes produced by the process. f(x,y) = 1/(.57)^2 What is the variance of the total length of both pipes? Give your answer to four decimal places. What is the probability that the second pipe (with length Y) is more than 0.1 feet longer than the first pipe (with length X)? Give your answer to four decimal places. Hint: Do not use calculus to get your answer.
