Suppose that prices of a gallon of milk at various stores in one town have a mean of $3.96 $ ⁢ 3.96 with a standard deviation of $0.12 $ ⁢ 0.12 . Using Chebyshev's Theorem, what is the minimum percentage of stores that sell a gallon of milk for between $3.72 $ ⁢ 3.72 and $4.20 $ ⁢ 4.20 ? Round your answer to one decimal place.
