Question 11 (1 point) A pair of variables, x and y, have a correlation coefficient of -1.0. How much of the variation in y is explained by the variation in x ( by the model) [as a percentage]? Note: 1- First convert your answer to the percentage and then round to 1 decimal place. Enter your final answer with 1 decimal place. 2- State the answer as a percentage without the percentage $. For instance, if the answer is 24.5%, only enter 24.5. Your Answer: Question 12 (1 point) What is the y-intercept of the line of best fit if 969 is the average of the values in the response variable, 403 is the average of the values in the explanatory variable, and 1.7 is the slope of the line of best fit? Note: 1- Only round your final answer to 2 decimal places. Enter your final answer with 2 decimal places. Your Answer: Question 13 (1 point) Assume that we have a regression model 5) = b0 + [91.x .Ifb1 =-1.20, 33,2250, and 5,, =o.9o, what is the fraction (percentage) of data's variation (variation in the response variable) accounted for by the model? Note: 1- Round all numbers (intermediate and final) to 4 decimal places. 2- Express your final answer as a percentage. However, enter the percentage without including the percentage symbol %. For instance, if your final answer is 0.652437, first round it to 4 decimal places, 0.6524, then convert it to a percentage, 65.24%, and then only enter 65.24 in the box. Your Answer: Question 14 (1 point) Assuming y is the dependent variable and x is the independent variable in a linear relationship, find the R2 of the relationship if b1= 1.5, S), = 3.4, and Sx = 1.0. Note: 1- Round any intermediate numbers to 4 decimal places. 2- Round your final answer to 2 decimal places. Enter your final answer with 2 decimal places. Your
