A poker-dealing machine is supposed to deal cards at random, as if from an infinite deck. You work for the state of Nevada, in the department that ensures casinos do not cheat their customers. In a test of the machine for randomness, you counted 1600 cards, and observed the following: Spades Hearts Diamonds Clubs 404 420 € 400 376* a. State your experimental hypothesis, as the inspector, for this test. b. State the null hypothesis for this test. c. Calculate the expected values for the above data. d. Calculate a Chi-Square value. Show your set up. e. Evaluate the Chi-Square value. [This means: State the degrees of freedom; compare your calculated value to the table value; accept or reject your null hypothesis; in light of this, evaluate your experimental hypothesis.] Finally, should you give the Casino a citation for a machine that does not deal randomly?
