What is the best predicted diastolic pressure for a person with a systolic reading of 146 ?3. Is the predicted value close to 91.0 , which was the actual diastolic reading?A. The predicted value is very close to the actual diastolic reading. B. The predicted value is not close to the actual diastolic reading. C. The predicted value is close to the actual diastolic reading. D. The predicted value is exactly the same as the actual diastolic reading.

ŷ = 6.69X - 706.18 ; 270.56; B. The predicted value is not close to the actual diastolic reading.

Step-by-step explanation:

Given the data below :

Systolic reading(x) :

117

134

150

113

138

113

144

145

Diastolic (y) :

85

74

86

55

75

80

106

841

A) Find the regression equation, letting the systolic reading be the independent (x) variable:

Using the online regression calculator :

The regression equation obtained is ;

ŷ = 6.69X - 706.18

Where ;

ŷ = dependent variable

6.69 is the gradient or slope

-706.18 is the intercept, where the line crosses the y - axis.

X - the independent variable (Systolic reading)

B.) Find the best predicted diastolic pressure for a person with a systolic reading of 146 .

ŷ = 6.69X - 706.18

ŷ = 6.69(146) - 706.18

ŷ = 270.56

Is the predicted value close to 91.0

B. The predicted value is not close to the actual diastolic reading.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
