Question

The weights of 2- pound bags of Best Dog Food are approximately normaly distributed with a gven mean and standard devation a. According to the Empirical Rule, what ercentage of the bags wil have weghts within 3 standard deviations of the mean?

A. 47.5%
B. 68%
C. 95%
D. 99.7 %

Answer 1

According to the Empirical Rule, approximately 99.7% of the bags will have weights within 3 standard deviations of the mean.

Step-by-step explanation:

The Empirical Rule states that for data that is bell-shaped and symmetric, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations of the mean, and approximately 99.7% falls within three standard deviations of the mean.

Since we are looking for the percentage of bags within 3 standard deviations of the mean, we can conclude that the answer is option D, 99.7%.
