1. Suppose that company A and company B are in the same industry sector, and the prices of their stocks, SX per share for company A and SY per share for company B, vary from day to day randomly according to a bivariate normal distribution with parameters μΧ=50, σχ= 10, μΥ-27, σΥ= 3, ρ=0.6. ) What is the probability that on a given day the price of stock for company A (x) is below $44? That is, find P(X<44). b)...
The percentage of marketable oysters that are collected from a large oyster bed varies from day to day. Assume that the random variable that describes this phenomenon follows the beta distribution with ? = 3 and ? = 2 . What is the probability that on any given day the percentage of marketable oysters is between 50% and 70%?
A quality control plan for an assembly line involves sampling n-10 finished items per day and counting Y, the number of defective items. If p denotes the probability of observing a defective item, then Ylp has binomial distribution with parameters n and p. But p varies from day to day and is assumed to have a uniform distribution over the interval [0, .25] a) Find the expected value of the number of defectives Y for any given day b) Find...
