A roulette wheel has 38 numbers: 1 through 36, 0, and 00. A ball is rolled and it falls into one of the 38 slots giving a winning number. The payout for betting on "The Top Line" (that is, the outcomes 0, 00, 1, 2, or 3) is $6 plus the dollar that was bet. The Situation: Suppose a gambler repeatedly bets $1 on "The Top Line." (a) Create a probability distribution function table for this situation. (b) Find the...
Answer the following questions: The team A has a winning probability whenever it plays. If the team plays 4 games then find the probability that A wins: (i) Only two games. (ii) At least one game. (iii) More than half of the games. (iv) What is the expected value and the standard deviation of the number of winning? (II) If X is a random variable with a distribution function: (x2+4x+8). F(x) = {322 -CsxsC cis constant. otherwise then find the...
More Practice With Normal Distributions. Assign your numbers for mean μ and standard deviation σ. Then select a number "A" below mean μ, and a number "B" above mean μ. Use Appendix Table for the Normal Distribution to find probability that x is between A and B: P (A < x < B). Here are steps to follow: convert A to z score (let's call it za), convert B to z score (let's call it zb).; From Appendix table find...
Consider a normal distribution with mean 25 and standard deviation 5. What is the probability a value selected at random from this distribution is greater than 25? (Round your answer to two decimal places.) Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.) μ = 14.9; σ = 3.5 P(10 ≤ x ≤ 26) = Need Help? Read It Assume that x has a...
Let y denote the number of broken eggs in a randomly selected carton of one dozen eggs. Supposing that the probability distribution of y is as follows below,determine the mean value of z = the number of unbroken eggs.µz =?y 0 1 2 3 4p(y) .65 .20 .12 .02 .01Suppose that for a given computer salesperson, the probability distribution of x = the number of systems sold in one month is given by thefollowing table.x12345678p(x).06.10.11.30.30.11.01.01(a) Find the mean value of...
Y have linear relation Y a X+ b, where a and b are real numbers? 3. A manufacturer produces piston rings for an automobile engine. It is known that ring diameter is approximately normally distributed with c-1.5mm. A random sample of 20 rings has a sample mean diameter of 75.012 mm and a sample standard deviation 1.25 mm. a. Can we conclude at.05 level of significance that the true mean piston diameter is at least 74.036 mm? Find the p-value...
4. At a local fundraising, you can purchase a ticket for $5, and select 3 numbers in any order from 1 to 20. The fundraisers also select 3 numbers. If you have all 3 winning numbers, then you win $50. If you have exactly 2 winning numbers, then you win $10. And finally, if you have exactly 1 winning number, then you win $5. (a) (6 points) Complete the table below. The Number of The Amount of The Probablity of...
