Pike Creek Golf Club currently has 375 members who pay annual dues to play golf on the course. Historical records show that 38% of the members use the course at least once a week during the summer season. To verify this, a random sample of 100 members was selected. a. Calculate the standard error of the proportion (round to 4 decimal places). b. What is the probability that 32 or more members from the sample used the course at least once a week? c. What is the probability that between 30 and 40 members from the sample used the course at least once a week?
