A study was performed on green sea turtles inhabiting a certain area. Time-depth recorders were deployed on 6 of the 76 captured turtles. The time-depth recorders allowed the environmentalists to track the movement of the sea turtles in the area. These 6 turtles had a mean shell length of 52.2 cm and a standard deviation of 6.8 cm. Complete parts a and b below. E Click the icon to view the shell length data of all 76 turtles. a. Use the information on the 6 tracked turtles to estimate, with 99% confidence, the true mean shell length of all green sea turtles in the area. (Round to one decimal place as needed.)
