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?

The scatter plot below shows the average cost of a designer jacket in a sample of years between 2000 and 2015. The least squares regression line modeling this data is given by yˆ=−4815+3.765x. A scatterplot has a horizontal axis labeled Year from 2005 to 2015 in increments of 5 and a vertical axis labeled Price ($) from 2660 to 2780 in increments of 20. The following points are plotted: (2003, 2736); (2004, 2715); (2007, 2675); (2009, 2719); (2013, 270). All coordinates are approximate. Interpret the slope of the least squares regression line. Select the correct answer below: 1.The average cost of a designer jacket decreased by $3.765 each year between 2000 and 2015. 2.The average cost of a designer jacket increased by $3.765 each year between 2000 and 2015. 3.The average cost of a designer jacket decreased by $4815 each year between 2000 and 2015. 4.

) A real estate magazine reported the results of a regression analysis designed to predict theprice (y), measured in dollars, of residential properties recently sold in a northern Virginiasubdivision. One independent variable used to predict sale price is GLA, gross living area(x), measured in square feet. Data for 157 properties were used to fit the model,? = β0 + β1x.The results of the simple linear regression are provided below.y = 96,600 +22.5x s = 6500 r2 = -0.77 t = 6.1 (for testing β1)Interpret the estimate of β0 the y-intercept of the line.a. About 95% of the observed sale prices fall within $96,600 of the least squares line.b. There is no practical interpretation, since a gross living area of 0 is a nonsensicalvalue.c. All residential properties in Virginia will sell for at least $96,600.d. For every 1-sq ft. increase in GLA, we expect a property's sale price to increase$96,600.
