Question

Everyone needs to cut costs, even those planning a wedding, according to the July 8, 2009, USA Today article “Today’s bride is ‘definitely the opposite of bridezilla.’” The article quoted the average wedding gown cost, based on information from The Knot Real Wedding Survey of 2008, as $1032. If we assume that the cost of wedding gowns is normally distributed with a standard deviation of $550, what is the probability that the mean cost of wedding gowns for a sample of 20 randomly selected brides-to-be is between $800 and $1200?
