Suppose that diameters of a new species of apple have a bell-shaped distribution with a mean of 7.25cm and a standard deviation of 0.43cm. Using the empirical rule, what percentage of the apples have diameters that are less than 6.82cm? Please do not round your answer.

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
