Problem-Based Learning Cost of Production Scenario 1: Preparation for New Business Shawn wants to start a new business by selling watermelon juice. In particular, he withdrew $500,000 of his saving from the commercial bank to cover his expense (for new business). Below is a list of costs associated with the production inputs: Table 1 Items Rent (Location) Wage Ingredient Machine Rental Electricity Fee Advertisement Fee Straw Table Rental Plastic Cup Plastic Cup Lids Plastic Bag Decoration Service Fee Cost $2,000 per day $160 per hour $6 per cup of juice $14 per day $21 per hour $73 per day $0.12 per straw $5.5 per day $0.7 per cup $0.1 per lid $0.5 per bag $35 per day Problem 1: Do we take into consideration the investment funds, Shawn's deposit ($500,000), when we compute the economic cost? Why? Problem 2: In Economics, we generally divide the production inputs into two categories, fixed input and variable input. Could you please categorize the production inputs, listed in Table 1, into fixed and variable inputs?

19. Length of Calls to the IRS. According to the IRS, taxpayers calling the IRS in 2017 waited 13 minutes on average for an IRS telephone assister to answer. Do callers who use the IRS help line early in the day have a shorter wait? Suppose a sample of 50 callers who placed their calls to the IRS in the first 30 minutes that the line is open during the day have a mean waiting time of 11 minutes before an IRS telephone assister answers. Based on data from past years, you decide that it is reasonable to assume that the standard deviation of waiting times is 8 minutes. Using these sample results, can you conclude that the waiting time for calls placed during the first 30 minutes the IRS help line is open each day is significantly less that the overall mean waiting time of 13 minutes? Use a = .05.
