You and a friend play a game where you each toss a balanced coin. If the upper faces on the coins are both tails, you win $5; if the faces are both heads, you win $8; if the coins do not match (one shows a head, the other a tail), you lose $4 (win (−$4)). Calculate the mean and variance of Y, your winnings on a single play of the game. Note that E(Y) > 0. E(Y) = $ V(Y) = How much should you pay to play this game if your net winnings, the difference between the payoff and cost of playing, are to have mean 0?

A social psychologist wants to see if altruism is significantly related to a person’s general health. He gets altruism scores and a measure of general health from the participants’ medical providers. The data are listed below. Higher altruism scores mean greater altruism, while high health scores = good health.

Scenario: Album Sales: A study was done to see whether getting radio airtime and spending money on advertisements accurately predicts the number of album copies sold. A random sample of 200 artists’ albums were tracked on the number of times their songs play on the central radio station, how much money (in thousands) they spent on advertisements, as well as the number (in thousands) of album copies were sold. A record company wanted to determine if there was a positive relationship between album sales and the other two variables (money spent on advertisements and number of albums sold) What is the Null and alternative hypotheses (based on context of study) in symbols and words:
