At a certain store, the distribution of weights of cartons of large eggs is approximately normal with mean 26 ounces (oz). Based on the distributions, which of the following intervals will contain the greatest proportion of cartons of large eggs at the store?

All of the intervals are 4 oz large. In a normal distribution, most of the area or probability comes from values around the mean.

24 to 28 oz captures the region that is 1 standard deviation from the mean and by the empirical rule, will comprise 68% of all eggs.

The exact proportions of each answer choice can also be calculated using a calculator or using \(z\)-scores.
