Question 1 ¨C Numerical Integration a) Probabilities from the standard normal distribution N(0,1) function below are found in Excel using the normsdist(z) function. Choose a numerical integration technique (i.e. Simpsons rule, trapezium rule etc) to approximate the integral used to find N(2.00). How does your answer compare to the normsdist function? Question 2 ¨C Monte Carlo Simulation From http://office.microsoft.com/en-us/excel/HA011118931033.aspx read the entire page, which introduces the idea of doing Monte Carlo simulation in Excel. On two separate worksheets, complete Problem 1 and Problem 2 at the bottom of that page. The Question: 1. A GMC dealer believes that demand for 2005 Envoys will be normally distributed with a mean of 200 and standard deviation of 30. His cost of receiving an Envoy is $25,000, and he sells an Envoy for $40,000. Half of all leftover Envoys can be sold for $30,000. He is considering ordering 200, 220, 240, 260, 280, or 300 Envoys. How many should he order? 2. A small supermarket is trying to determine how many copies of People magazine they should order each week. They believe their demand for People is governed by the following discrete random variable. Demand Probability 15 .10 20 .20 25 .30 30 .25 35 .15 The supermarket pays $1.00 for each copy of People and sells each copy for $1.95. They can return each unsold copy of People for $0.50. How many copies of People should the store order? |
