Use the Housing Interest Rate database (see DATA at bottom of this question)

In this part using Housing Interest Rate database, the objective is to compare the variation in the FIXED_RATE between two periods; before 2000 and after year 2000.

• i) Using descriptive statistics measures to interpret the shape of FIXED_RATE variable, calculate any outlier(s) finally verify whether if the empirical rule applies to the FIXED_RATE distribution.  Use an appropriate graph to confirm your findings.

• ii) Use a random generating procedure to draw a random sample of size 80 with respect to the “before and after year 2000 “factor.  Indicate which sampling method you used.  Using your sample data, calculate which period shows more variation in the FIXED_RATE.  Using the sample data, what is the   sampling error of FIXED_RATE?

A company is evaluating a revenue arrangement to determine proper revenue recognition. The contract is for manufacturing 20 race cars. The customer needs the cars by May 1, 2021. The customer provides a bonus payment of $320,000 if all cars are delivered by the May 1 deadline. The bonus is reduced by a fourth of the total available bonus amount (i.e., reduced by $320,000 divided by 4) each week that the cars are delivered after the deadline until no bonus is paid if the cars are delivered after May 22nd, 2021. The company has good historical data for estimating the probabilities of completion at different dates. It estimates an equal probability (20%) for each full delivery outcome. How much should the company recognize as revenue related to this bonus?
