A survey conducted by the American Automoble Association showed that a family of four spends an average of s215.60 per day while on vacation. Suppose a sampie of 64 famies of four vecationing at Niagara Faits resulted in a sampie mean of $254.45 per day and a sampie standard deviation of 126. 30. (a) Develop a 9S oonhdence interval estimate of the mean amount spent per day in dollars by a famly of four visiting Nagara Fals. (Round vour antwers to the nearest cent.) (b) Based on the confidence interval Rom part (a), does it appear that the population mean amount spent per day by famies visiting Nagara falts difers frem the mean reported by the Amencan Automeble Association? Explain O Yes. The upper limit for the confdence interval for the population mean at Niagara Fals s less than overall average daily vecation expenditure of s215.60 per day. This suggests the population mean at Nagara fals is less than the overal average. Ves. The lower limit for the confidence interval for the population mean at Niagara Fals ia greater than overail average daly vacation expendture of s215.60 per day. This suggests the population mean at Nagara Falls is greater than the overall average. O Yes. The overall averege daily vacation expenditure of $215.60 per day is between the upper and lower limits of the confidence interval for the population mean at Niagara Fas. This suggests the population mean at Niagara Fals is less than the overall average ONo. The overall average dally vacation expenditure of $215.60 per day is between the upper and lower mits of the confidence interval for the population mean at Niagara Fas. Ts suggests we cannot determine if the population mean at Niagara Falls is greater than the overall average dally vacation expenditure. O No. The lower limit for the confidence interval for the population mean at Nagara Fals is greater than overall average dally vacation expenditure of $215.60 per day This suggests we cannot determine if the population mean at Niagara Falis is greater than the overal average daily vacation expenditure.

A survev conducted by the American Automobile Association showed that a family of four spends an average of s215.60 per day while on vacation. Suppose a sampie of 64 families of four vecationing
at Niagara Fails resulted in a sample mean of $254.45 per day and a sampie standard deviation of 176,50.
(a) Develop a 95 confidence interval estimate of the mean amount spent per day in dollars by a family of four visiting Nagara fals. (Round your answers to the nearest cent.)
to s
(b) Based on the confidence interval Rom part (a), does it appear that the population mean amount spent per day by famlies visiting Niagara fals aters trom the mean reported by the Amencan
Automobile Association? Explain.
O Yes. The upper limit for the confdence interval for the population mean at Niagara Fals is less than overall average daily vacation expenditure of s215.60 per day, This suggests the
population mean at Niagara Falls is less than the overall average.
Ves. The lower limit for the confidence interval for the population mean at Niagara Falls is greater than overail average daily vacation expenditure of S215.60 per day. This suggests the
population mean at Nagara Falls is greater than the overall average.
O Yes. The overall average daily vacation expenditure of $215.60 per day is between the upper and lower limits of the confidence interval for the population mean at Nagara Fals. This
suggests the population mean at Niagara Fals is less than the overall average.
O No. The overall average dally vacation expenditure of $215.60 per day is between the upper and lower bmits of the confidence interval for the population mean at Niagara Fals. This
suggests we cannot determine if the population mean at Niagara Fals is greater than the overall average dally vacation expenditure.
ONo. The lower limit for the confidence interval for the population mean at Niagara Falls is greater than overall average dally vacation expenditure of $215.60 per day. This suggests we
cannot determine if the population mean at Niagara Falis is greater than the overal average daily vacation expenditure.
