In the Northern Hemisphere, dolphins swim predominantly in a counterclockwise direction while sleeping. A group of researchers wanted to know whether the same was true for dolphins in the Southern Hemisphere. They watched 8 sleeping dolphins, and found that they swam in a clockwise direction while sleeping the following percentages of time. Assume that this is a random sample and that this variable has a normal distribution in the population. What is the 99% Confidence Interval for the mean time swimming clockwise in the Southern Hemisphere? Fill in the blanks - Do not include the % sign, and give answers to one decimal place. Use statistical table C on page 709 of your textbook. 77.7, 84.8, 79.4, 84.0, 99.6, 93.6, 89.4, 97.2
