In exercise 12, the following data on x = average daily hotel room rate and y = amount spent on entertainment (The Wall street Journal, August 18, 2011) lead to the estimated regression equation ŷ = 17.49 + 1.0334x. For these data SSE = 1541.4.
City | Room Rate ($) |
Entertainment ($) |
Boston | 148 | 161 |
Denver | 96 | 105 |
Nashville | 91 | 101 |
New Orleans | 110 | 142 |
Phoenix | 90 | 100 |
San Diego | 102 | 120 |
San Francisco | 136 | 167 |
San Jose | 90 | 140 |
Tampa | 82 | 98 |

- b. Develop a 95% confidence interval for the
mean amount spent on entertainment for all cities that have a daily room rate of $89. - c. The average room rate in Chicago is $128. Develop a 95% prediction interval for the amount spent on entertainment in Chicago.

If a sample of 25 pairs of data yields a correlation coefficient, r, of 0.390 and the scatterplot displays a linear trend, can you use the regression equation to make predictions, assuming your x-values are within the domain of the data set? Choose your answer from the multiple choice answers below
A.) Yes, because rcrit = 0.396 and the regression coefficient, r, is less than this value.
B.) Yes, because rcrit = 0.381 and the regression coefficient, r, is greater than this value.
C.) No, because rcrit = 0.381 and the regression coefficient, r, is greater than this value.
D.) No, because rcrit = 0.396 and the regression coefficient, r, is less than this value.
Given the equation of a regression line is y = -5.5x - 9.4, what is the best predicted value for y given x = -3.1? Assume that the variables x and y have a significant correlation.
Ch 13. 7: Refer to the Lincolnville School District bus data. First, add a variable to change the type of engine (diesel or gasoline) to a qualitative variable. If the engine type is diesel, then set the qualitative variable to 0. If the engine type is gasoline, then set the qualitative variable to 1. Develop a regression equation using statistical software with maintenance cost as the dependent variable and age, odometer miles, miles since last maintenance, and engine type as the independent variables.

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.
