spaces provided. Bus Maintenance (Questions 1 through 3) The regional transit authority wants to study the age of their buses and their annual maintenance cost. The following table is a part of the results of a Regression Analysis obtained from data on a sample of 10 buses. R Square 0.8725 Coefficients Intercept 220.00 Age 131.67 Help the regional transit authority predict the annual maintenance cost in dollars given the age of a bus in years. 1. Develop the estimated regression model ($\hat{y} = b_0 + b_1x$). (Roud to two decimal places.) 2. State and interpret $b_1$. 3. Use the model to predict the annual maintenance cost for a bus that is 6 years old. (Round to the nearest cent.)

Step 1
From the table, we have bo = 220.00 and b1 = 131.67. Therefore, the estimated regression model is: y = 220.00 + 131.67x Show moreā¦

The regional transit authority for a major metropolitan area wants to determine whether there is a relationship between the age of a bus and the annual maintenance cost. A sample of 10 buses is shown in the data file AgeCost. (20 points). a. Develop a scatter chart for these data. What does the scatter chart indicate about the relationship between age of a bus and the annual maintenance cost? (4 points). b. Use the data to develop an estimated regression equation that could be used to predict the annual maintenance cost given the age of the bus. What is the estimated regression model? (4 points). c. Test whether each of the regression parameters ĆĀ²0 and ĆĀ²1 is equal to zero at a 0.05 level of significance. What are the correct interpretations of the estimated regression parameters? (4 points). d. How much of the variation in the sample values of annual maintenance cost does the model you estimated in part (b) explain? (4 points). e. What do you predict the annual maintenance cost to be for a 3.5-year-old bus? (4 points).

Bus Maintenance. The regional transit authority for a major metropolitan area wants to determine whether there is any relationship between the age of a bus and the annual maintenance cost. A sample of 10 buses resulted in the following data. a. Develop the least squares estimated regression equation. b. Test to see whether the two variables are significantly related with $\alpha=.05$. c. Did the least squares line provide a good fit to the observed data? Explain. d. Develop a $95 \%$ prediction interval for the maintenance cost for a specific bus that is 4 years old.

The regional transit authority for a major metropolitan area wants to determine whether there is any relationship between the age of a bus and the annual maintenance cost. A sample of 10 buses resulted in the following data: Age of Bus (years) Maintenance Cost ($) 350 370 480 520 590 550 750 800 790 950 Develop the least squares estimated regression equation. Test to see whether the two variables are significantly related. Did the least squares line provide a good fit to the observed data? Explain. Develop a 95% prediction interval for the maintenance cost for a specific bus that is 4 years old.
