Question

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 wins a small prize, p, is 0.40. If a random sample of 40 players is selected, then ?̂ is the proportion of players in the sample who win a small prize.

What is the mean of the sampling distribution of ?̂?

μp^=

What is the standard deviation of the sampling distribution of ?̂? Give your answer precise to three decimal places.

σp^=

A carnival game gives players a 10% chance of winning every
time it is played. A player plays the game 10 times. A. Let X be
the number of times the player wins in 10 plays. What is the most
probable value of X? B. what is the probability that the player
will win at least once?

on a game show a contestants have a chance to spin a wheel. the
wheel is divided into slots, half of the slots say win and half say
lose. there is a pointer above the top of the wheel, if the pointer
points to a win slot when the wheel stops then the contestant wins
cash prize. if the pointer points to a lose slot then the
contestant wins nothing. The contestant spins the wheel 3 times.
Let x be...

A carnival game involves a spinner that is designed so that in
20 percent of spins the player will win a prize. A random sample of
100 spins will be observed and the random variable X = number of
times in the sample that the player won a price will be recorded.
For the questions below, consider the process of finding the
indicated probability by using the normal distribution as an
approximation, including making the appropriate continuity
correction. (Note that...

Suppose you went to a fundraiser and you saw an interesting
game. The game requires a player to select five balls from an urn
that contains 1000 red balls and 4000 green balls. It costs $20 to
play and the payout is as follows:
Number of red balls
Prize
0
$0
1
$20
2
$25
3
$50
4
$100
5
$200
Questions:
1) Is this a binomial experiment? If so, explain what p, q, n,
and x represent and find...
