- 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?arrow_forwardIn a simple linear regression problem, the following sum of squares are produced: Σ,-)²=200, Σ,-)² = 50, and - y)² =150 percentage of the variation in y that is explained by the variation in x is: a. 25% b. 75% c. 33% d. 50% Thearrow_forward5.

We have chosen a random sample of 96 students just finishing their first year of college, and for each student we've recorded her score on the standardized test and her grade point average for her first year in college. For our data, the least-squares regression equation relating the two variables score on this standardized test (denoted by x and ranging from 400 to 1600) and first-year college grade point average (denoted by y and ranging from 0 to 4) is y = 0.8884 +0.0020x. The standard error of the slope of this least-squares regression line is approximately 0.0016. Based on these sample results, test for a significant linear relationship between the two variables by doing a hypothesis test regarding the population slope B₁. (Assume that the variable y follows a normal distribution for each value of x and that the other regression assumptions are satisfied.)…arrow_forwardMight we be able to predict life expectancies from birthrates?
