Seams Personal advertises on its website that 95% of customer orders are received within four working days. They performed an audit from a random sample of 500

Part A: Can we use a normal approximation? Explain (5 points)
Part B: If Seams Personal customers really receive 95% of their orders within four working days, what is the probability that the proportion in the random sample of
500 orders is the same as the proportion found in the audit sample or less? (5 points)
