Chapter 14.4, Problem 6Q

A sample of ten 40-W light bulbs was taken from each of three manufacturing plants. The bulbs were burned until failure. The number of hours that each remained lit is listed in the following table.

Plant 1 Plant 2 Plant 3
905 1109 571
1018 1155 1346
905 835 292
886 1152 825
958 1036 676
1056 926 541
904 1029 818
856 1040 90
1070 959 2246
1006 996 104
  • (a) Test the hypothesis that the median lives of bulbs produced at the three plants are all the same. Use the 0.05 level of significance.

  • (b) Are the mean lives of bulbs produced at the three plants all the same? Use the analysis of variance with a=0.05.

  • (c) Change the observation “2246” in the third column to “1500” and redo part (a). How does this change affect the hypothesis test?

  • (d) Change the observation “2246” in the third column to “1500” and redo part (b). How does this change affect the hypothesis test?

Problem 1.We consider a two-period binomial model with the following properties: each period lastsone (1) year and the current stock price is S0 = 4. On each period, the stock price doubleswhen it moves up and is reduced by half when it moves down. The annual interest rateon the money market is 25%.  We consider four options on this market:ˆ A European call option with maturity T = 2 years and strike price K = 5;ˆ A European put option with maturity T = 2 years and strike price K = 5;ˆ An American call option with maturity T = 2 years and strike price K = 5;ˆ An American put option with maturity T = 2 years and strike price K = 5.(a) Find the price at time 0 of both European options.(b) Find the price at time 0 of both American options. Compare your results with (a)and comment.(c) For each of the American options, describe the optimal exercising strategy.(d) We assume that you sell the American put to a market participant A for the pricefound in (b). Explain how you act on the market…

Note: The purpose of this problem below is to use computational techniques (Excelspreadsheet, Matlab, R, Python, etc.) and code the dynamic programming ideas seen inclass. Please provide the numerical answer to the questions as well as a sample of yourwork (spreadsheet, code file, etc.).We consider an N-period binomial model with the following properties: N = 60, thecurrent stock price is S0 = 1000; on each period, the stock price increases by 0.5% whenit moves up and decreases by 0.3% when it moves down. The annual interest rate on themoney market is 5%. (Notice that this model is a CRR model, which means that thebinomial tree is recombining.)(a) Find the price at time t0 = 0 of a (European) call option with strike price K = 1040and maturity T = 1 year.(b) Find the price at time t0 = 0 of a (European) put option with strike price K = 1040and maturity T = 1 year.(c) We consider now, that you are at time t5 (i.e. after 5 periods, which represents 1month later). Assume that the stock…
