The weight of oranges growing in an orchard is normally distributed with a mean weight of 5.5 oz. And a standard deviation of 1 oz. Using the empirical rule, determine what interval would represent weights of the middle 68% of all oranges from this orchard.

If 20% of a number is 35, what is 50% of that number?
