Answer 1

The bag weight is 1.5 standard deviation below the mean value. Standard deviation is found with the help of variance.

What is standard deviation ?

The standard deviation is the positive square root of the variance of this data set. Variance of a data set is the sum of squared differences of the data values from its mean to the total count of data values.

The mean value is 4.10 ounce

Standard deviation= 0.10 ounce

The formula for the standard deviation is found as;

$\rm Z= \frac{x-\mu}{\sigma} \\\\ Z= \frac{3.95-4.10}{0.10} Z=\frac{-0.15}{0.10} \\\\ Z=-1.5$

Hence, the bag weight is 1.5 standard deviation below the mean value.
