A normal turtle weighs between 20 and 25 lbs. In a random survey of 800 male turtles and 754 female turtles, it was found that 273 male turtles and 210 female turtles were normal weight. Construct a 99% confidence interval of the difference in the proportion of male turtles and female turtles who are normal weight. Then interpret the interval.

Interpret this confidence interval. There is a 99% probability that either a male turtle or a female turtle are normal weight. We are 99% confident that the point estimate for the the difference of male turtles and female turtles who are normal weight. With 99% confidence the interval calculated contains the difference of sample proportions of male turtles and female turtles who are normal weight. With 99% confidence the interval calculated contains the difference of population proportions of male turtles and female turtles who are normal weight
