Develop a regression forecast model using the interest rate as the predictor (independent) variable. The regression model is: Number of loans =a+bx Answer for a. Answer to two decimal places, and use a minus sign if necessary. the answer for b (in y=a+bx ). Answer to two decimal places, and use a minus sign if necessary. If the interest rate is 15 , the bank should expect to make loans (round your answer to the nearest whole number). If the interest rate is 5.5m the bank should expect to make loans (round to the nearest whole number)
