Using the Empirical Rule, it is found that 99.7% of the weights are between 180 g and 480 g.

What does the Empirical Rule state?

It states that, for a normally distributed random variable:

  • Approximately 68% of the measures are within 1 standard deviation of the mean.
  • Approximately 95% of the measures are within 2 standard deviations of  the mean.
  • Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Hence, the bounds of the interval containing 99.7% of the weights is given by:

  • 330 - 3 x 50 = 180 g.
  • 330 + 3 x 50 = 480 g.
