c) Calculate a measure to determine the strength of the linear relationship between X and Y

Transcribed Image Text:The relationship between body mass index (BMI) and systolic blood pressure in males 50 years of age is investigated. A random sample
14 males is selected and their BMIl 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) = 11.104.
The average and variance of the systolic blood pressure is Y = 132 and Var(Y) = 205.
The covariance between X and Y is Cov(X,Y) = 35.1.
For the estimated regression equation Y = Bo + B,X, it was found that 3
