Answer:
The predicted diastolic blood pressure of people with 113 mm Hg systolic blood pressure is 74 mm Hg.
Explanation:
The general form of a regression equation is:

Here,
y = dependent variable
x = independent variable
α = intercept
β = slope
The formula to compute the slope and intercept are:

The value of
as compute in the table attached below.
Compute the value of α and β as follows:

Thus, the regression equation of diastolic blood pressure based on systolic blood pressure is:

Compute the value of y for x = 113 as follows:


Thus, the predicted diastolic blood pressure of people with 113 mm Hg systolic blood pressure is 74 mm Hg.
