Question:-6 people were randomly selected and their systolic (x) and diastolic (y) blood pressures were measured. Systolic 138 130 135 140 120 125 Diastolic 92 91 100 100 80 90 Σx = 788, Σy = 553, Σx 2 = 103794, Σy 2 = 51245, Σxy = 72876 (Data)

(A)If systolic blood pressure increases by one unit, then:-

(a) diastolic blood pressure decreases by about 15.5 units

b) diastolic blood pressure decreases by about 0.82 units.

(c) diastolic blood pressure increases by about 15.5 units

(d) diastolic blood pressure increases by about 0.82 units

(e) the response of the diastolic blood pressure cannot be predicted (Explain in detail how..??)

Expert Solution

We get the regression equation as-

y^ = 0.82 * x + (-15.50)

If systolic blood pressure increases by one unit, then:-

(d) diastolic blood pressure increases by about 0.82 units

Hope this will help you. Thank you :)
