Suppose that the probabilities of a customer purchasing 0, 1, or 2 books at a book store are 0.3, 0.4, and 0.3 respectively. What is the standard deviation of this customer's book purchases?
Problem 2 - Bayesian Inference Nisqually, Inc. sells books A,B,C on line. Each customer buys 0 or 1 copy of each title. a. Mrs. Independence Day, the company's data mining expert, makes the assumptions that: i) a customer decides to buy a book independently of what other books (s)he buys and independently of other customers. ii) all customers buy according to the same joint probability distribution PABC = PAPeP. with PA(1)0.6, PB(1) 0.3, Pc1) 0.4. For example, the probability that...
Question Help Suppose that a customer is purchasing a car. He conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. He conducts this experiment 15 times on each car and records the number of miles driven.

ABC Company is a book order company that sells books via internet. When a customer places an order, the system checks books data for completeness and determines the price, then the customer is asked about his/her details and payment information. If the customer account is correct, the system checks customer details and determine discount. The system verifies the credit by checking the accounts receivable. If credit is OK then the system fills the order, else it requests repayment. To fill...
An info source produces 0 and 1 with probabilities 0.3 and 0.7, respectively. the output of the source is transmitted via a channel that has probabilities of error (turning a 1 into a 0 or a 0 into a 1) equal to 0.2 1) what is the probability that at the output a 1 is observed? 2) What is the probability that a 1 was output of the source if at the output of the channel a 1 is observed.
For customers purchasing a refrigerator at a certain appliance store, let A be the event that the refrigerator was manufactured in the U.S., B be the event that the refrigerator has an icebreaker, and the event that the customer purchased an extended warranty. Relevant probabilities are: P(A)= 0.75 P(B|A) = 0.9 P(B|A′) = 0.8 P(C|A ∩ B) = 0.8 P(C|A ∩ B′) = 0.6 P(C|A′ ∩ B) = 0.7 P(C|A′ ∩ B′) = 0.3 What is the probability that the...
pls explain as much as possible, thanks!!
The number of customers waiting for gift-wrap service at a department store is an rv x with possible values 0, 1, 2, 3, 4 and corresponding probabilities 0.1, 0.2, 0.3, 0.25, 0.15. A randomly selected customer have 1. 2. or 3 packages for wrapping with probabilities 0.55,0.25, and 0.2, respectively. Let the total number of packages to be wrapped for the customers waiting in line (ume that the number of packages submitted by...
Data have been accumulated on the heights of children relativeto their parents. Suppose that the probabilities that a tall parentwill have a tall, medium-height, or short child are 0.6, 0.2, and0.2, respectivly; the probabilities that a medium-height parentwill have a tall, medium-height, or short child are 0.1, 0.7, and0.2, respectively; and the probabilities that a short parent willhave a tall, medium-height, or short child are 0.2, 0.4, and 0.4respectively. a) Write down the transition martix for this Markovchain. b) What...
QUESTION 1 (39 MARKS) Suppose you choose 2 books that you are planning to read (the books selected must contain both Malay and English). Thus, there will be a total of 2n number of books, where n is the number of team members. Assume that this 2n is the size of population that is approximately normally distributed with mean and standard deviation ơ a) List the number of pages for each of the 2n books as in Table 1. Let...
