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. If the two population proportions are the same, the difference between them will be zero. Does your confidence interval provide significant evidence for a difference of male turtles and female turtles who are normal weight? Explain. yes, since 0 is not contained within our confidence interval no, since 0 is contained within our confidence interval yes, since the proportion of female turtles cannot be negative no, since negative proportion of male turtles make sense
