To Find:

what percentage of the bags will have weights within 3 standard deviations of the mean

Solution:

The weight of 2 pounds of  bags are normally distributed.

Hence the curve will have two tailed hypothesis with normal distributed curve.

<em>So Using Empirical Rule which state the following :</em>

For normal distributed mean  and S.D. it has three parts as follows:

1) 68% of data falls within the first S.D. from the mean.

2)95% falls within 2nd S.D.

3)99.7 % falls within 3rd S.D.

we have to calculate for the 3rd S.D.

Hence the data will falls 3rd S.D. will be 99.7%
