Each time you buy a pack of cards for a collectible card game, you get 10 random cards out of a pool of 25. The cards in a pack are guaranteed to be distinct, and all cards are equally common. You buy two packs of cards; let X be the number of cards you get twice (once from each pack). What is the name of the distribution of X, and its parameters?

Suppose you are interested in buying a new Lincoln Navigator or Town Car. You are standing on the sales lot looking at a model with different options. The list price is on the vehicle. As a salesperson approaches, you wonder what the dealer invoice price is for this model with its options. The following data are based on a random selection of these cars of different models and options. Let y be the dealer invoice (in thousands of dollars) for the given vehicle. x 32.4 32.9 36.1 44.0 47.8 y 30.4 31.0 32.0 42.1 42.2 (b) Use a 10% level of significance to test the claim that ρ > 0.

Make a prize distribution table for a six player game. Prizes are variable but can range from $5 - $200 (Betting options are in $5, $10, $30 & $50 intervals) depending on bets. Each player's prizes are independent from other players. Since the game has a betting system we will need to make categories of winnings. Option for 0/6 winners Option for 1/6 winner Option for 2/6 winners:

A student is interested in whether students who study with music playing devote as much attention to their studies as do students who study under quiet conditions. He randomly assigns participants to either the music or no-music condition and has them read and study the same passage of information for the same amount of time. Participants are then all given the same 10-item test on the material. Their scores appear below. Scores on the test represent interval-ratio data and are normally distributed. music no-music 6 10 5 9 6 7 5 7 6 6 6 6 7 8 8 6 5 9 Please use the appropriate statistical test to analyze these data, and design a hypothesis testing process, get the conclusion about whether students who study with music playing devote as much attention to their studies as do students who study under quiet conditions. If significant, compute the effect size, interpret this, and draw a graph representing the data.
