Roulette An American roulette wheel has 18 red slots among its 38 slots. To test if a particular roulette wheel is fair, you spin the wheel 50 times and the ball lands in a red slot 31 times. The resulting P-value is 0.0384.

(a) Interpret the P-value in context.

(b) Are the results statistically significant at the a = 0.05 level? Explain. What conclusion would you make?

c) The casino manager uses your data to produce a 99% confidence interval for p and gets (0.44, 0.80). He says that this interval provides convincing evidence that the wheel is fair. How do you respond?

An American roulette wheel has 38 slots and 18 of these are red. If the wheel is fair, then the probability of it landing on red is 18/38. At a certain roulette table, after 190 spins it landed red on 78 of the spins. This is less than the expected value. Could chance explain the difference, or is this sufficient evidence otherwise? Use a hypothesis test as follows. (a) Compute the expected value of the number of "reds" after 190...
