A group conducted a survey of 13,000 brides and grooms married in the United States and found that the average cost of a wedding is $23,858. Assume that the cost of a wedding is normally distributed with a mean of $23,858 and a standard deviation of $5,700.

(a)What is the probability that a wedding costs less than $18,000? (Round your answer to four decimal places.)

(b)What is the probability that a wedding costs between $18,000 and $32,000? (Round your answer to four decimal places.)

(c)What is the minimum cost (in dollars) for a wedding to be included among the most expensive 5% of weddings? (Round your answer to the nearest dollar.)$
