The concentration of dissolved solids and the turbidity of stream are measured simultaneously for five separately days selected days selected at random throughout a year. the data are as follows Do mg/L 400 550 700 800 500 Turbidity JTU 5 30 32 58 20 since turbidity is easier to measure, a regression equation may be used to predict the concentration of dissolved solids on the basis of known turbidity. Assume that the variance of dissolved solid concentrations is constant with turbidity.

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?
