You wish to test the following claim (Ha) at a significance level of α = 0.02. Ho: μ = 82.1 Ha: μ > 82.1 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 11 with mean M = 100.5 and a standard deviation of SD = 18.5. What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value =

14.5. The Joseph Brant Manufacturing Company makes athletic footwear. Processing of production orders is as follows: At the end of each week, the production planning department prepares a master production schedule (MPS) that lists which shoe styles and quantities are to be produced during the next week. A production order preparation program accesses the MPS and the operations list (stored on a permanent disk file) to prepare a production order for each shoe style that is to be manufactured. Each new production order is added to the open production order master file stored on disk. Each day, parts department clerks review the open production orders and the MPS to determine which materials need to be released to production. All materials are bar-coded. Factory workers work individually at specially designed U-shaped work areas equipped with several machines to assist them in completely making a pair of shoes. Factory workers scan the bar codes as they use materials. To operate a machine, the factory workers swipe their ID badge through a reader. This results in the system automatically collecting data identifying who produced each pair of shoes and how much time it took to make them. Once a pair of shoes is finished, it is placed in a box. The last machine in each work cell prints a bar- code label that the worker affixes to the box. The completed shoes are then sent to the warehouse. REQUIRED a. Prepare a data flow diagram of all operations described. b. What control procedures should be included in the system? ant neoduction processes have a scrap rate of 15% and a return rate of 3%.

a) Practice creating a binomial tree given a set of par coupon yields and then with a set zero coupon prices. We did the former in class and the latter for homework. Make up your own set of yields or prices to do this. b) Once the tree is complete, create and price any zero coupon and coupon bond. What if the coupon bond was not standard? For instance, the coupon could be specified to start low and step up. c) Create a puttable and then a callable bond and use your tree to price them. What if I told you the issuer would only call the bond at par if the price went above \$101 instead of \$100. How would you price that bond? d) Can you calculate the price sensitivity of the bond if all the rates in the tree change by the same amounts up and then down? Can you interpret your results?

7. Let X₁, X₂, ..., Xₙ be a random sample from a normal distribution with mean μ and standard deviation σ. a) Find the maximum likelihood estimators of μ and σ. b) Show that the estimator of μ is unbiased but the estimator of σ is biased. c) Compute the bias of the estimator of σ and comment on it. Hence, write a function of this estimator that is unbiased, find its variance, and show that it is consistent. d) Find the Cramer-Rao lower bound variance of σ and hence find the absolute efficiency of the unbiased estimator you proposed in (c).
