(a) Perform a hypothesis test to assess whether there is sufficient evidence to conclude that the chance of success for patients with condition A is better than 50%.
(b) Construct a two-sided 99'v confidence interval for the difference between the success probabilities for patients with condition A and with condition B.
(c) Perform a chi-square goodness of fit test to investigate whether there is sufficient evidence to conclude that the success probabilities are different for patients with condition A and with condition B. What is your conclusion?
