A survey conducted by the British Columbia Automobile Association (BCAA) 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 in Victoria resulted in a sample mean of $252.45 per day and a sample standard deviation of $74.50.Calculate a 95% confidence interval estimate of the mean amount spent per day by a family of four visiting Victoria.Hint: Refer to Section 8.2 in your textbook, and use T.INV in Excel to find the t value.Based on your confidence interval from part (a), does it appear that the population mean amount spent per day by families visiting Victoria differs from the mean reported by BCAA? Explain.

Question

A survey conducted by the British Columbia Automobile Association (BCAA) 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 in Victoria resulted in a sample mean of $252.45 per day and a sample standard deviation of $74.50.

Calculate a 95% confidence interval estimate of the mean amount spent per day by a family of four visiting Victoria.

Hint: Refer to Section 8.2 in your textbook, and use T.INV in Excel to find the t value.
Based on your confidence interval from part (a), does it appear that the population mean amount spent per day by families visiting Victoria differs from the mean reported by BCAA? Explain.
