1. Based on a sample of 100 leatherback sea turtles, researchers conclude that the average amount of time a leatherback sea turtle can hold its breath is about 73 minutes, with a 95% confidence interval of (70,76).

A. Which of these is the best description of what that means?

i.95% of leatherback sea turtles can hold their breath for between 70 minutes and 76 minutes.

ii. Given a random leatherback sea turtle, we have 95% confidence that it can hold its breath for between 70 minutes and 76 minutes.

iii. We have 95% confidence that among the turtles in the researchers' sample, the average amount of time one of those turtles can hold its breath

is between 70 minutes and 76 minutes.

iv. We have 95% confidence that among all leatherback sea turtles, the average amount of time a leatherback sea turtle can hold its breath is between 70 minutes and 76 minutes.
