With Obesity on the rise, a Doctor wants to see if there is a linear relationship between the Age and Weight and estimating a person's Systolic Blood Pressure. Using that data, find the estimated regression equation which can be used to estimate Systolic BP when using Age and Weight as the predictor variable.

  • A.

    Systolic BP = 31.73252234 + 0.965183151(Age) + 2.666383416(Weight)

  • B.

    Systolic BP = 31.73252234 + 0.938835263(Age) + 0.309246373(Weight)

  • C.

    Systolic BP = 31.73252234 + 0.984797135(Age) + 0.969825398(Weight)

  • D.

    Systolic BP = 11.05638371+ 0.230153049(Age) + 0.120862651(Weight)

  • Systolic BP Age in Yrs. Weight in lbs.

Answer:

Using the regression equation function using the variables Age(x1) and wgt(x2) as independent with BP (y) as dependent variables,

ŷ = 0.93884X1 + 0.30925X2 + 31.73252

Option b
