95% of M&Ms weigh between 0.803 and 0.947 grams according to the Empirical Rule.

Using the Empirical rule, we have: x̅ - 2s = 0.875 - 2 (0.036) = 0.875 - 0.072 = 0.803 x̅ - 2s = 0.875 + 2 (0.036) = 0.875 + 0.072 = 0.947 Hence, 95% of M&Ms weigh between 0.803 and 0.947 grams according to the Empirical Rule.
