Normal Approximation for Proportions

Return to exercise on Binomial Lab. Use the sample proportion to approximate the probability of getting at most 25 heads in 30 flips of a biased coin with probability .6 of getting a head.

A corporation receives 100 applications for a position from recent college graduates in business. Assuming that these applications can be regarded as a random sample of all such graduates, what is the probability that between 25% and 35% of them are women if 30% of all recent college graduates in business are women?
