You run a house flipping business where you buy thousands of houses across the country, hire contractors to fix them up, and try to sell them. For any given house, you figure there is a 50%/50% chance of gaining 60% or losing 40%. This means your expected return per house is 0.5x0.60+0.5x(-0.40) = 0.10 = 10%. The variance per house is 0.5x(0.60-0.10)2 + 0.5x(-0.40-0.10)2 = 0.25. If the covariance between houses is 0.10, what is the variance of your portfolio of thousands of houses

The management of Brinkley Corporation is interested in using simulation to estimate the profit per unit for a new product. The selling price for the product will be $45 per unit. Probability distributions for the purchase cost, the labor cost, and the transportation cost are estimated as follows: Procurement Cost ($) Probability Labor Cost ($) Probability Transportation Cost ($) Probability 10 0.25 20 0.10 3 0.75 11 0.45 22 0.25 5 0.25 12 0.30 24 0.35 25 0.30 Compute profit per unit for the base-case, worst-case, and best-case scenarios. Construct a simulation model to estimate the mean profit per unit. Why is the simulation approach to risk analysis preferable to generating a variety of what-if scenarios? Management believes the project may not be sustainable if the profit per unit is less than $5. Use simulation to estimate the probability the profit per unit will be less than $5.
What would this normal probability plot lead you to believe about the normality of the population from which the data were taken? 2.0 1.0 -1.0 -2.0 120 130 140 150 160 170 180 190 The points show a pattern straying from a straight line, indicating that the population is not approximately normal. The points appear to be randomly scattered, indicating that the population is probably approximately normally distributed. The points roughly follow a linear pattern, indicating that the population is probably approximately normally distributed. The points roughly follow a linear pattern, indicating that the population is probably not approximately normally distributed. z-Score
Yorkies Company has fixed costs of $80,000 per month. Variable costs are $12 per item produced. The selling price per unit is fixed at $20. From the past company data, you have determined that Yorkies Company's monthly output follows a normal probability distribution with mean 11,100 and variance 550,000 . Calculate the chance that Yorkies will make a loss this month. a.11% b.10% c.9% d.7% e.7%
*Question Six* The management of a supermarket wants to adopt a new promotional policy of giving free gift to every customer who spends more than a certain amount per visit at this supermarket. The expectation of the management is that after this promotional policy is advertised, the expenditure for all customers at this supermarket will be normally distributed with mean 400 £ and a variance of 900 £2. What is the probability that the expenditure of the first customer exceeds the expenditure of the second customer by at least 20 £?
