A survey conducted by the American Automobile Association showed that a family of four spends an average of $215.60 per day while on vacation. Suppose a sample of 64 families of four vacationing at Niagara Falls resulted in a sample mean of $252.45 per day and a sample standard deviation of $74.50. Develop a 95% confidence interval estimate of the mean amount spent per day by a family of four visiting Niagara Falls.
