An accountant for'a large department store has the business objective of developing a model to predict the amount of time it takes to process Invoices, Data are collected from the past 32 working days, and the number of invoices processed and completion time (in hours) are recorded with the accompanying results, Complete parts (a) through (h) below Click the icon to view the Invoice data a. Assuming a mhear relationship, use the least-squares method to compute the regression coefficients by and by (Round to three decimal places as needed ) b, Interpret the meaning of the by. In this problem. slope, Interpret the slope, If appropriate. Choose the correct answer below. Q) A. The slope indicates that for each additional hour of completion time, the number of invoices is estimated to Increase by a valve equal to by. B. It is not appropriate to interpret the slope because it is outside the range of observed numbers of invoices C C. It is not appropriate to interpret the slope because it it outside the range of observed completion times (1.D. The slope Indicates that for each additional invoice, the completion time is estimated to increase by a number of hours equal to byAn accountant for a large department store has the business objective of developing a model to predict the amount of time it takes to process Invoices.
