Family Vacation Expenses A survey conducted by the American Automobile Association AAA 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 Niagra Falls resulted in a sample mean of $252.45 per day and a sample standard deviation of $74.50. In excel: Develop a 95% confidence interval estimate of the mean amount spent per day by a family of four visiting Niagra Falls. Based on the confidence interval from part a., does it appear that the population mean amount spent per day by families visiting Niagra Falls differs from the mean reported by the American Automobile Association? Explain.
