Suppose researchers are interested in estimating the true mean litter size of a certain type of rat in a certain geographical location.A sample of 25 rats yielded a sample mean litter size of 8.2 pups, with an associated 95% confidence intervalof 7.6 to 8.8.Supposethe assumptions of the procedure they used were met.Of the following options, which one is the best interpretation of that interval?

We can be 95% confident that the true mean litter size for this type of rat in this area lies between 7.6 to 8.8.

In repeated sampling, 95% of the 95% confidence intervals calculated in this manner will capture the sample mean litter size.

We can be 95% confident that the sample mean size of the 25 litters lies between 7.6 and 8.8.

95% of litters for rats in this area have between 7.6 and 8.8 pups.
