used in a simple random sample. Surveys were done of the general population of the US and they hardly ever use simple random samples because chances are everyone will ne inclusion. Weights are variables that determine how much each respondent counts. Distributions In this table you will find the gender, age department, position, tenure with company, extrinsic or extrinsic. Below you can see my findings and the probability that I have came up with. This information will be very helpful. It breaks

gather data from the college which allowed them to develop a table for the probability distribution of the wait for repair services on JET’s copier. To model the probability of wait times in the JET Copies simulation, the JET partners generated a random number representing the probability of an occurrence of a breakdown. They then programmed a VLOOKUP function to match this breakdown probability to the corresponding “Repair Time in Days” column of the table. The result is the simulated time to

future of the four of you was discussed and a decision was taken to release one of you. I can’t tell you who - the Chairman is writing to you all immediately. However, I can say that we were unable to make the decision on merit, so we made it at random. The Chairman took one of four cards, each of which had one of your names on the back!” “So, I have a one in four chance of being out of work after Christmas”, said Alain. He felt relieved, as he had thought the odds might be worse. “But of course

Lecture 3 Supplement Annoying Proof of a Useful Result Proof1 that E(ea+bx̃) = ea+b+½Var(x̃) I. The Normal Distribution The probability density function of a normal distribution is 1 2 v 1 y e 2 v 2 which has the property, for any y and v, that 1 2 v 1 y e 2 v 2 dy 1 II. Fun with Completing the Square! Now suppose a b~ is distributed N a b , b 2 2 . x Let’s find the because a bx a b bx expected

For this data, a probability distribution table was developed and programmed into excel. Once the probability table is loaded into excel, they are averaged into a random number range that generates numbers from 0.00 to 1.0. The system then generated an average number days it would take to repair the machine base to the random number generated. 2. Write a brief description of how you implemented the intervals between break downs. When the company looked at the number of intervals between

If A and B are independent events with P(A) = 0.20 and P(B) = 0.60, then P(A|B) is 0.2000 In the notation below, X is the random variable, c is a constant, and V refers to the variance. Which of the following laws of variance is not correct? V(c) = 0 V(X + c) = V(X) V(X + c) = V(X) + c V(cX) = c2 V(X) Which of the following statements is always correct? P(A and

Introduction This paper will answer the question whether or not JET Copies, a new copier company established by three friends, should purchase a smaller copier as a backup for the primary copier when the primary copier is not in service. The owners of the company have purchased a primary copier similar to the one in the dean’s school of business. During making their decision to purchase, the owners received positive information from the seller regarding the copier reliability. The price of the primary
