Concept explainers
Can you use the annual revenues generated by National Basketball Association (NBA) franchises to predict franchise values? Figure 2.14 on page 66 shows a
a. Assuming a linear relationship. use the least-squares method to compute the regression coefficients
b. Interpret the meaning of the Y intercept.
c. Predict the mean value of an NBA franchise that generates
revenue.
d. Compute the coefficient of determination.
e. Perform a residual analysis on your results and evaluate the regression assumptions.
f. At the 0.05 level of significance. is there evidence of a linear relationship between the annual revenues generated and the value of an NBA franchise?
g. Construct a 95% confidence
h. Construct a 95% prediction interval of the value of an individual NBA franchise that generates
i. Compare the results of (a) through (h) to those of baseball franchises in Problems 13.8, 13.20, 13.30, 13.46, and 13.62 and European soccer teams in Problem 13.83.
