oilet Flushing In the Healthy Handwashing Survey conducted by Bradley Corporation, it was found that 64% of adult Americans operate the flusher of toilets in public restrooms with their foot. Suppose you survey a random sample of 740 adult American women aged 18–24 years. Use the normal approximation to the binomial to approximate the probability that (a)  exactly 490 of those surveyed flush toilets in public restrooms with their foot.  (b)  no more than 490 of those surveyed flush toilets in public restrooms with their foot.   (c)  at least 503 of those surveyed flush toilets in public restrooms with their foot. What does this result suggest?
