About 8080% of all female heart transplant patients will survive for at least 3 years. SeventySeventy female heart transplant patients are randomly selected. What is the probability that the sample proportion surviving for at least 3 years will be less than 7575%? Assume the sampling distribution of sample proportions is a normal distribution. The mean of the sample proportion is equal to the population proportion and the standard deviation is equal to StartRoot StartFraction pq Over n EndFraction EndRootpqn.
