Question: What is the least squares regression line and what are
What is the least squares regression line, and what are the least squares point estimates?
Answer to relevant QuestionsWhen a least squares line is fit to the 30 observations in the Fresh detergent data, we obtain SSE = 2.806. Calculate s2 and s. The MINITAB output of a simple linear regression analysis of the data set for this case (see Table 13.3 is given in Figure 13.11. Recall that a labeled MINITAB regression output is on page 482. What does the distance value measure? How does the distance value affect a confidence or prediction interval? Total variation = 13.459; SSE = 2.806; b1 = 2.6652 The service time case a. Use the explained variation and the unexplained variation as given on the computer output to calculate (within rounding) the F(model) statistic. b. Utilize the F(model) statistic and the appropriate ...
