Multiple Choice

A null hypothesis is that the probability is 0.7 that a new drug will provide relief in a randomly selected patient. The alternative is that the probability of relief is greater than 0.7. Suppose the treatment is used on 500 patients and there are 380 successes. How would a p-value be calculated in this situation?

A) Find the chance of 380 or more successes, calculated assuming the true success rate is greater than 0.7.
B) Find the chance of 380 or more successes, calculated assuming the true success rate is 0.7.
C) Find the chance of fewer than 380 successes, calculated assuming the true success rate is greater than 0.7.
D) Find the chance of fewer than 380 successes, calculated assuming true success rate is 0.7.
