Answer question 15-18!! THANK YOU
15. The total sum of squares (TSS) is best defined as a. the sums of squares of the dependent variables b. the total variation of Y around its mean. c. the sums of squares of the predicted values d. the variation of Y around its mean plus the variation of Y around the predicted values. 16. The error sum of squares term is used as a criterion for determining bo and b1 because a. the sum of errors will always equal zero b. the term can be solved for exact values of bo and b1 c. both bo and bi can be easily calculated using the sum of squares term. d. all of these 17. When using the Regression tool in Excel the dependent variable is entered as the a. X-range. b. Y-range c. dependent-range. d. independent-range 18. What is the correct range for R values? b. (1R s1) C. (0 R"-1) d. (0sR2Explanation / Answer
15.
Correct Answer:
B
TSS involves the measurement of the sum of the squares of differences of y observation from its mean value.
