An online travel agent that specializes in cruises wanted to compare the cost of cruising to different destinations on various cruise lines. The following random sample data show the average cost of a seven-day cruise in a standard room to two locations. Assume the population variances for the cruise fares for these destinations are equal. Complete parts a through c. Location 2 Sample mean Sample standard deviation Sample size. Location 1 $994 $135 8 $928 $128 11 a. Construct a 98% confidence interval to estimate the difference between the average rates of cruising to location 1 vs. cruising to location 2. The 98% confidence interval is (). (Round to two decimal places as needed.)
