You will perform a Chi-Square test test. For the hypothesis test make sure to report the following steps:

  1. Identify the null hypothesis, Ho, and the alternative hypothesis, Ha.
  2. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.
  3. Find the critical value(s) and identify the rejection region(s).
  4. Find the appropriate standardized test statistic. If convenient, use technology.
  5. Decide whether to reject or fail to reject the null hypothesis.
  6. Interpret the decision in the context of the original claim.

A sports researcher is interested in determining if there is a relationship between the type of sport and type of team winning (home team versus visiting team). A random sample of 526 games is selected and the results are given below. Test the claim that the type of team winning is independent of the type of sport. Use α = 0.01.

Basketball

Soccer

Baseball

Two buyers bid in an auction for a single object. Each can bid any integer amount from $0 to $10. The two bids are made simultaneously and independently of each other. The buyers’ respective values are v1 = 5 and v2 = 10. The bidder with the higher bid wins (obtains the object) and pays the amount of his own bid. However, the bidder who does not win the auction and thus does not get the object is also obliged to pay half of his own bid. In case of a tie in the bids bidder 2 wins.
(a) Specify the best responses to pure strategies for both bidders. (5 points)
(b) Identify the pure strategy NE of the game. (3 points)
(c) Find all dominated strategies for each bidder. (5 points)
(d) Now restrict the possible bids to $4 and $5, and identify all pure and mixed strategy NE in this game. (7 points)

What data is selected to in excel to calculate MAD for part b?

The graduate assistant for the Santa Clara Broncos football team has compiled the following statistics: Year wins avg offensive yards avg interceptions 1 10 500 2 2 8 450 4 3 5 250 10 4 10 485 1 5 7 399 4 6 11 521 2 7 4 158 15 8 11 525 0 9 8 485 4 10 4 300 9 11 5 350 9 12 7 375 9 13 2 150 15 14 5 380 5 a. Using Excel, develop a linear regression model for wins, employing average offensive yards and average interceptions. b. Calculate the MAD for your model. c. Calculate R, F, and t statistics and interpret them.

  1. Stacy and Leslie are playing a very simple gambling game. They toss a coin and Stacy wins if it comes up “heads” while Leslie wins if it comes up “tails.” After 12 hours of gambling, Leslie begins to suspect that Stacy has been cheating because Stacy has won more games. Leslie accuses Stacy, but Stacy pleads innocent and proposes to test Leslie’s claim by doing an experiment in which the coin is tossed 14 times.
  1. State the null and alternative hypotheses for this experiment.
  2. If α = .01, what is the rejection region?
  3. They do the experiment and “heads” occurs 8 times. What can they conclude? What if heads comes up 12 times?
  4. Let’s assume that Stacy actually is cheating because she is using a coin that is biased to come up “heads” 55% of the time. What was the power of the experiment they did?
  5. Given the power of the experiment, was Stacy clever or stupid to propose it as a test to Stacy?

Write code for a game of picking match sticks. You must make sure that the computer always wins. The game is as follows

There are 26 matchsticks initially. The computer will ask the user to pick anywhere between 1 and 4 matchsticks. The player (whether the user or the computer) who has to pick up the last matchstick (or matchsticks) is the loser. You will have to use a combination of branching and looping commands with appropriate prompts and the input() function.

Hint: The computer will always win if you code appropriately. When coding consider the following:

1. You must first print a statement to the screen which explains the game

2. You must print the remaining matchsticks after each round

3. You must finally print the final statement about who won the game.

In order to always ensure that the computer wins: the sum of the matchsticks chosen by the user and the computer should equal 5.

NB: Include picture of python code

1.Create full program in Java that will simulate a Rock Paper Scissors Game You will create the code so that when the program is run the user will see in the console the following: We are going to play rock paper scissors. Please choose 1 for Rock 2 for Paper or 3 for scissors. The program will have your choice which is the integer-valued typed in by the user and compChoice which will be the randomly generated value of either 1 2 or 3. You will test all the ways the user wins if he or she beats the computer using || with if and then you will check all the ways that computer could win using else if with || and lastly the only other thing that can happen would be a tie if both choices are the same for the default else. Display what was chosen and what was randomly chosen by the computer and who wins or if there is a tie. For extra credit, you can use dialog boxes and show images.

Three Digits from {1,2,3,4,5,6,7} are chosen and arranged in a row without replacement.

  1. Determine the number of different outcomes we could obtain
  2. Find the probability of each event:
    1. The digit 1 appears
    2. All digits are even
    3. At least one digit is even
    4. The number is divisible by 5
