Question 11 Item 11 A study was conducted to investigate whether the mean numbers of snack bars sold at two airport convenience stores, C and D, were different. For ten randomly selected days, the number of snack bars sold at each store was recorded, and the sample mean number of snack bars for each store was calculated. A two-sample tt-test for a difference in means will be conducted. Have all conditions for inference been met? Yes, all conditions have been...

11) A wheel with three numbers on it-zero, one, and two-is spun so that there is a 40% chance that the wheel lands on zero, a 20% chance the wheel lands on one, and a 40% chance the wheel lands on two. You pay $1.50 to spin the wheel, and you get back the amount in dollars of the number that the wheel lands on. Compute the expected value of the game.

In a certain lottery, players pick 5 numbers (without replace) from the numbers 1-50 and an additional number (possibly repeated from the first set) from the numbers 1-30. A set of 6 numbers with these restrictions is then chosen uniformly at random. The player wins based on how many of their numbers matched the randomly chosen number. (a) What is the probability that the player chooses all 6 numbers correctly? (b) What is the probability that the player chooses exactly...
