Question 20 1 pts What is the expected monthly bank charge in dollars for a company with an annual sales revenue of 5.6 million dollars that conducts foreign transactions? Question 21 1 pts Consider the regression shown above for estimating bank charges. Which one of the following statements is TRUE? O About 95% of the observed service charges fall within +/- $2,700 of the least squares line. Companies can expect to be charged $50 less per month if they do not conduct any foreign currency transActions, when compared with those that do, assuming an equivalent level of annual sales revenue. The banks charge a monthly fixed fee, which is on average equal to $2,700. O For every $2 million increase in annual sales revenue, we expect the bank charge to increase by $2000.Question 22 1 p Consider the regression shown above for estimating bank charges. What is the difference between the estimated regression equations for companies that conduct foreign transactions and those that do not? There is no difference O They have different slopes O It is impossible to tell with the information provided O They have different interceptsQuestions 20 - 22 are based on the following information. A large bank charges local companies for using its 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. The first independent variable is the company's annual sales revenue (X1 ) measured in millions of dollars and the second independent variable is whether the company conducts foreign currency transactions ( X2 = 1 if yes, and 0 otherwise). Data for 121 companies who use the bank's services were used to fit the model: Y = Bo + BIX1 + 32X2 +E The results are provided below. Y = -2, 700 + 2000X1 + 50X2 the two-tail p-value = 0.0034 (for testing B1 = 0), the two-tail p-value = 0.01 (for testing B2 = 0)
