The data is Income (available in the quiz directions), have two variables, consumption, andIncome (in 1,000 dollars). We want to predict consumption based on Income, i.e., Income isthe independent variable.Use Excel to calculate the regression equation to answer the question.The 85% confidence interval for the slope is:O (0.430997, 0.753221)(0.3683183, 0.8158995)O(0.40670, 0.77752)O (0.32167, 0.86255)(0.39397, 0.79025)O (0.24305, 19.30748)

To answer your question, based on the confidence interval provided, the correct option is:(0.430997,…

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
