In a data set with 12 observations, you try fitting two regression models. The esti- mated models are summarized as: Model 1: Y(hat) =3.5 + 2x; SSR= 5, and SSE= 10; Model 2: Y(hat) =3.0 + 1.5x + 0.4^2; SSR=23, and SSE=7 (a) Calculate R2 for both models. b. for both models test the null hypothesis that all the regression coefficients other than the intercept are 0.

Olympic Pole Vault The graph in Figure 7 indicates that in recent years the winning Olympic men’s pole vault height has fallen below the value predicted by the regression line in Example 2. This might have occurred because when the pole vault was a new event there was much room for improvement in vaulters’ performances, whereas now even the best training can produce only incremental advances. Let’s see whether concentrating on more recent results gives a better predictor of future records. (a) Use the data in Table 2 (page 176) to complete the table of winning pole vault heights shown in the margin. (Note that we are using x=0 to correspond to the year 1972, where this restricted data set begins.) (b) Find the regression line for the data in part ‚(a). (c) Plot the data and the regression line on the same axes. Does the regression line seem to provide a good model for the data? (d) What does the regression line predict as the winning pole vault height for the 2012 Olympics? Compare this predicted value to the actual 2012 winning height of 5.97 m, as described on page 177. Has this new regression line provided a better prediction than the line in Example 2?

At one of the San Diego area beaches, there has been a problem with thefts in the summer months. A random sample of summer days was selected. For each day, the number of street cameras (X) in the beach area and the number of reported thefts (Y) were recorded. The data was analyzed to produce the results below: The regression equation is: Thefts = 9.78 – 0.493*(cameras) On a certain day there were 5 cameras in the area and 3 reported thefts. Calculate the residual for this day. 8.301 -4.315 4.315 3.301 7.315
