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

 and

Step-by-step explanation:

According to the question,

 is the random variable 'Proportion of players in the sample who do not win a prize'.

Now, here

P(A player do not win a prize) = 0.6

So,

and

                             =

                             = 0.24

so,

                             =

                             =

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
