Quiz 10 Simple linear regression Started: May 11 at 1:26pm QUIZ INSTRUCTIONS Question 1 1 pts When using the SLOPE function to compute the slope of the least-squares regression line the order of the parameters matters (unlike the case for the CORR function EL True False Question 2 1 pts To compute the coefficient of determination in the screenshot below, we need to enter the following formula in cell B8. 1 Mean of X 34 2 Mean of Y 18 4 St Dev of X. 4 5 St Dev of YE 7 Correlation 0.93 8 coefficient of Determination- B7A2 O SQRT(B7 O COD (B1, B2 O COEFF,DEET (B1,B2

Explanation / Answer

1) True, Otherwise, the new slope obtained will be 1/Slope(original)

2) The correct answer is A. (B7^2) . Coefficient of determiantion = correlation squared

3) False, different intercepts for x on y and y on x regressions

4) The first option is correct

5) True. This is one way of shwoing equation
