Question: 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.

1. If the amount spent by a family of four while vacationing at Niagara Falls is skewed to the right, would you expect the median amount spent to be greater than or less than $252.45? Explain.
2. Is it necessary to assume a normal distribution on the population to estimate the value of the mean spending per day? Explain.
3. Use the sample data to construct a 95% confidence interval estimate for the mean amount spent per day by a family of four visiting Niagara Falls
4. Based on the confidence interval from part c), does it appear that the population mean amount spent per day by families visiting Niagara Falls differs from the mean reported by the American Automobile Association? Explain
