These plots also show the least squares regression lines. In the following statements RSS stands for residual sum of squares, while SSreg stands for regression sum of squares. Which one of the following statements is true? (a) RSS for model 1 is greater than RSS for model 2, while SSreg for model 1 is greater than SSreg for model 2. (b) RSS for model 1 is less than RSS for model 2, while SSreg for model 1 is less than SSreg for model 2. (c) RSS for model 1 is greater than RSS for model 2, while SSreg for model 1 is less than SSreg for model 2.

When s is unknown (as is usually the case) replacing σ by S results in T= bˆ 0 − b 0 2 S 1 +x n SXX = bˆ 0 − b 0 ~ tn − 2 se(bˆ ) 0 2 where se (bˆ 0 ) = S 1 n + x SXX is the estimated standard error of bˆ0, which is given directly by R. 32815. 24 2 Simple Linear Regression For testing the hypothesis H 0 : b 0 = b 00 the test statistic is T= bˆ 0 − b 00 ~ t n − 2 when H 0 is true. se(bˆ ) 0 R provides the value of T and the p-value associated with testing H 0 : b 0 = 0 against H A : b 0 ϶ 0. 0001.

These two sets of times can be found on book web site in the file called changeover_times. txt. 2. 5. We wish to develop an equation to model the relationship between Y, the change-over time and X, the dummy variable corresponding to New and hence test whether the mean change-over time is reduced using the new method. , x = 1 if the time corresponds to the new change-over method and 0 if it corresponds to the existing method). Regression Output from R Coefficients: Estimate Std. 0260 --Signif. 02604 *** * We can test whether there is significant reduction in the change-over time for the new method by testing the significance of the dummy variable, that is, we wish to test whether the coefficient of x is zero or less than zero, that is: H 0 : b1 = 0 against H A : b1 < 0 We use the one-sided “<” alternative since we are interested in whether the new method has lead to a reduction in mean change-over time.
