TABLE 13-1

A large national bank charges local companies for using their services. A bank official reported the results of a regression analysis designed to predict the bank’s charges (Y)-measured in dollars per month-for services rendered to local companies. One independent variable used to predict the service charge to a company is the company’s sales revenue (X)-measured in millions of dollars. Data for 21 companies who use the bank’s services were used to fit the model:

E(Y) = b0 + b1X

The results of the simple linear regression are provided below.

Y= -2,700 + 20X, SYX = 65, two-tailed p value = 0.034 (for testing b1)

Referring to Table 13-1, interpret the estimate of b0, the Y-intercept of the line.
A) There is no practical interpretation since a sales revenue of \$0 is a nonsensical value.
B) All companies will be charged at least \$2,700 by the bank.
C) About 95% of the observed service charges fall within \$2,700 of the least squares line.
D) For every \$1 million increase in sales revenue, we expect a service charge to decrease \$2,700.

Referring to Table 13-1, interpret the estimate of the standard deviation of the random error term (standard error of the estimate) in the model.
A) About 95% of the observed service charges equal their corresponding predicted values.
B) About 95% of the observed service charges fall within \$65 of the least squares line.
C) For every \$1 million increase in sales revenue, we expect a service charge to increase \$65.
D) About 95% of the observed service charges fall within \$130 of the least squares line.

Referring to Table 13-1, interpret the p value for testing whether b1 exceeds 0.
A) For every \$1 million increase in sales revenue, we expect a service charge to increase \$0.034.
B) Sales revenue (X) is a poor predictor of service charge (Y).
C) There is sufficient evidence (at the alpha = 0.05) to conclude that sales revenue (X) is a useful linear predictor of service charge (Y).
D) There is insufficient evidence (at the alpha = 0.10) to conclude that sales revenue (X) is a useful linear predictor of service charge (Y).

Referring to Table 13-1, a 95% confidence interval for b1 is (15, 30). Interpret the interval.
A) We are 95% confident that the sales revenue (X) will increase between \$15 and \$30 million for every \$1 increase in service charge (Y).
B) At the alpha = 0.05 level, there is no evidence of a linear relationship between service charge (Y) and sales revenue (X).
C) We are 95% confident that the mean service charge will fall between \$15 and \$30 per month.
D) We are 95% confident that average service charge (Y) will increase between \$15 and \$30 for every \$1 million increase in sales revenue (X).
