You obtain the regression equation y = 4.028x-16.406 with a correlation coefficient of r = 0.75. Predict what value of the explanatory variable will, on average, correspond to a value of 90 for the response variable. Round the answer to 1 decimal place. License Points possible: 10 This is attempt 1 of 1.

Explanation / Answer

given euation of regression line is Y= 4.028X - 16.406

and here given that value of responce variable is Y=90

X=explanatory variable, Y=responce

hence predicted value (X)= (Y+16.406)/4.028

X= (90+16.406)/4.028

X=26.4165=26.4
