Approximately 63
b. Approximately 2758
c. Approximately 40
d. Approximately 70

Answers

Answer 1

Answer:

The predicted value received on the exam when the percentage attendance is 70 is ( a. Approximately 63).

To find the predicted value of the exam score when the percentage attendance is 70, to use the regression equation provided:

Y = Intercept + Attendance × X

From the regression statistics that the intercept (Intercept) is 39.39027309 and the coefficient for percentage attendance (Attendance) is 0.340583573.

Substituting the values into the equation:

Predicted value = 39.39027309 + 0.340583573 × 70

Calculating:

Predicted value ≈ 39.39027309 + 23.84485711

Predicted value ≈ 63.2351302
