It is believed that approximately 75% of American youth now have private health insurance due to the health care law. Suppose this is true, and let X equal the number of American youth in a random sample of n = 15 with private health insurance. (a) How is X distributed? (b) Find the probability that X is at least 10. Hint: You may want to use Excel. (c) Find the probability that X is at most 10. Hint: You may want to use Excel. (d) Find the probability that X is equal to 10. (e) Give the mean, variance, and standard deviation of X.

A. A recent study found that 2% of Americans admitted they had driven while intoxicated in the prior month. If a problem asks you to find the probability that 200 or fewer people in a population of 10,000 drive under the influence of alcohol, how do you solve the problem after finding the probability in the z-table? A. Subtract one from the probability you find in the z-score tables B. The probability that equates to the z-score is the answer C. Tis problem cannot be answered with the z-tables D. Take the probability you find in the z-score tables and subtract from one

Your friend Phil, asks you what you think about a new scratch-off lottery game. It costs $10 to play this game, There are two outcomes for the game (win, lose) and the probability that a player wins a game is 60%. A win results in $15, for a net win of $5 ($15 minus the $10 paid to play). The probability distribution for x� (the amount of money a player wins or loses) in a single game is as follows:
