Q2 (4 pts): Ben is the financial analyst of the firm and focuses on the revenue generated (as output) by each dollar cost. Therefore, he evaluates multifactor productivity for each Lab, whe different costs should be all considered as input. Identify the tab that has the best multifactor productivity and its multifactor productivity (rounded to with flive decimal digits if not a wh number). Q3 (4 pts): Follow Ben's use of multifactor productivity, however calculate multifactor productivity for the firm's operations with three Labs together (instesd of separately). What is this overall multifactor productivity (rounded to with five decimal dieits if not a whole number)? Q4 (4 pts): Top management's goal had been a minimum yield of 7 . on each dollar cost (i.e, a multifactor productivity of at least 1.07 ) from all three Labs. if this goal was not attained las month, the management would plan to reduce the $30,000 monthly corporate overhead next month. However, next month's revenue per test, labor hours used, labor hourly cost, mater cost, and operating experses at each Lab will be about the same as last imonth. In this case, the management would wonder about the threshold for monthly corporate overhead; that is, once monthly corporate overhead is lowered to reach this threshold, top management's goal of a minimum 7N vield will just start to be met. Answer "N/A" if the management's goal was achieved already last month, otherwise calculate this threshold (expressed as a whole number, no decimal digits)
