Seventy percent of bicycles sold by a certain store are mountain bikes. Let X be the number of 100 randomly selected purchases that are for mountain bikes. Verify the binomial setting. Verify that the sampling distribution of X is approximately normal. What is the approximate probability that At most 75 are mountain bikes? Between 60 and 75 (inclusive) are mountain bikes? More than 80 are mountain bikes?
