It costs $6.75 to play a very simple game, in which a dealer gives you one card from a deck of 52 cards. If the card is a heart, spade, or diamond, you lose. If the card is a club other than the queen of clubs, you win $10.50. If the card is the queen of clubs, you win $49.00. The random variable x represents your net gain from playing this game once, or your winnings minus the cost to play. What is the mean of x, rounded to the nearest penny? $i

There is a very popular lottery in which a ticket is called a scratcher. In this lottery, 46% of the scratchers are winning ones. Suppose that we will take a random sample of 8 scratchers. Let p represent the proportion of winning scratchers from the sample. Consider the sampling distribution of the sample proportion p. Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed. (a) Find u^ (the mean of the sampling distribution of the sample proportion). (b) Find o^ (the standard deviation of the sampling distribution of the sample proportion).

To get a sample of 50 students for a student services survey, an assistant principal uses the calculator command "randInt(1,72,5)" to pick five numbers between 1 and 72. He goes to those five pages in the 72-page directory and chooses the ten students pictured on each of those five pages. Will this sampling strategy result in a random sample from the population under consideration?
