Working with Bayes' theorem calculations.

Experience has shown a company that the cost of delivering a small package within 24 hours is $14.80. The company charges $15.50 for shipment but guarantees to refund the charge if delivery is not made within 24 hours. If the company fails to deliver only 2% of its packages within the 24-hour period, what is the expected gain ...continues

Hypothesis Testing A. For the statement: The mean amount of Pepsi in cans is at least 12 oz. Express the null hypothesis and the alternative hypothesis in symbolic form. B. Find the z value for the following : The claim is u(mu) =12, and the sample statistics include n =36, xbar = 12.19 and s = .11 C. Determine whether the ...continues

Probability - Rolling a Dice

A person rolls a pair of six-sided dice, which are equally likely to come up any number from 1 to 6. If the person rolls a seven he gets $0. If he rolls any other number, he can choose either to win that amount or play the game again from the start. This person believes that the best strategy is to keep rolling until he gets a " ...continues

ANOVA Table and Hypothesis Testing

Fill in the following ANOVA table and perform the hypothesis testing. Refer to attachment.

Joint Distributions (multiple choice)

John makes a mark on a straight stick that is 1 meter in length; you assign a uniform distribution to the location of the mark(uniform over the entire length of the stick). John cuts the stick at that mark, making two sticks. John then takes the larger stick and makes a mark on it; you assign a uniform distribution to the loc ...continues

e-value of a distribution

A person runs one mile to his house as fast as he can. It is equally likely that he will run at an average speed of 3 miles per hour, 6 miles per hour, and 9 miles per hour. What is the e-value of your distribution of the time it will take this person to get home? Multiple choice answers: a) 8 minutes b) 10 minutes c) ...continues

Probability and sample mean

PVC pipe is manufactured with a mean diameter of 1.01 inches and a standard deviation of 0.003 inches. What is the probability that a random sample of 9 sections of pipe will have a sample mean diameter between 1.009 inches and 1.012 inches? Assume the central limit theorem holds. Mulitple choice answers: a) 15.9% b) 37.8% ...continues

e-value of a distribution: coin flips

Bill flips a coin that can land heads or tails, and you assign equal probabilities to each, with all flips mutually irrelevant. Bill will flip the coin until he sees a consecutive sequence of tails, tails, tails. What is the e-value of your distribution of the number of flips until this happens? For example, if Bill flips HHT ...continues
