For the following data set: (a) Use a TI-84 calculator to compute the coefficient of determination. Round the answer to at least three decimal places. The coefficient of determination is 0.480. Alternate Answer: 0.48 (b) How much of the variation in the outcome variable is explained by the least-squares regression line? Round the answer to at least one decimal place. The percentage of the variation in the outcome variable is explained by the least-squares regression line is %.

Use the results from Problem 27 in Section 4.1 and Problem 19 in Section 4.2 to: (a) Compute the coefficient of determination, $R^{2}$. (b) Construct a residual plot to verify the requirements of the least-squares regression model. (c) Interpret the coefficient of determination and comment on the adequacy of the linear model.

Calculate the coefficient of determination, given that the linear correlation coefficient, r, is -0.225. What does this tell you about the explained variation and the unexplained variation of the data about the regression line? a. The coefficient of determination(R2) = 0.051. That is, 5.1% of the variation is unexplained and 94.9% of the variation is explained. b. The coefficient of determination(R2) = 0.051. That is, 5.1% of the variation is explained and 94.9% of the variation is unexplained. c. Not enough information is given.

00:02 Hello students, today we will discuss about this question.
00:04 In this question we are given that we need to interpret the coefficient of determination and comment on the adequacy of the linear model.
00:38 That is equal to question mark.
00:40 So here first of all we need to interpret the coefficient of determination...
