Suppose that, as part of a game at a charity carnival, players are invited to spin a wheel for a chance at winning either a small, medium, or large prize. The wheel is constructed so that the probability that a player does not win a prize, rho, is 0.60. If a random sample of 40 players is selected, then p^Hat is the proportion of players in the sample who do not win a prize. What is the mean of the sampling distribution of p^Hat? mu _p^Hat = Number _______ What is the standard deviation of the sampling distribution of p^Hat? Give your answer precise to three decimal places. sigma _p^Hat = Number _______

There are 20 members of a basketball team.(a) The coach must select 12 players to travel to an away game. How many ways are there to select the players who will travel?(b) From the 12 players who will travel, the coach must select her starting line-up. She will select a player for each of the five positions: center, right forward, left forward, right guard, left guard. How many ways are there for her to select the starting line-up?(c) From the 12 players who will travel, the coach must select her starting line-up. She will select a player for each of the five positions: center, right forward, left forward, right guard, left guard. However, there are only three of the 12 players who can play center. Otherwise, there are no restrictions. How many ways are there for her to select the starting line-up?

Lorelei evaluates the expression StartFraction 12 factorial Over (12 minus 10) factorial 10 factorial EndFraction to determine how many different groups of ten she can make out of twelve items. Her solution: Subtract within parentheses and simplify: StartFraction 6 factorial Over (2) factorial 5 factorial EndFractionExpand: StartFraction 6 times 5 times 4 times 3 times 2 times 1 Over 2 times 1 times 5 times 4 times 3 times 2 times 1 EndFractionDivide out common factors: StartFraction 6 Over 2 times 1 EndFractionBecause 6 divided by 2∙1 is 3, there are 3 ways to choose the groups. Which statements describe Lorelei’s solution? Check all that apply.Her work is correct. Her answer is correct.In step 1, the subtraction cannot be completed before the factorial of each number is calculated.In step 1, 12! divided by 10! is not equivalent to 6! divided by 5!.In step 3, the dividing out of common factors was performed incorrectly. There are sixty-six ways to choose ten items from twelve.

Weights of the vegetables in a field are normally distributed. From a sample Carl Cornfield determines the mean weight of a box of vegetables to be 172 oz. with a standard deviation of 8 oz. He wonders what percent of the vegetable boxes he has grouped for sale will have a weight less than 164 oz. _Carl calculates the z-score corresponding to the weight 164 oz. _ Using the table (column .00), Carl sees the area associated with this z-score is 0. Carl rounds this value to the nearest hundredth or 0. _Now, Carl subtracts 0.50 - 0.34 = 0._ or _%
