The bag weight is 1.5 standard deviation below the mean value. Standard deviation is found with the help of variance.
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;
[tex]\rm Z= \frac{x-\mu}{\sigma} \\\\ Z= \frac{3.95-4.10}{0.10} Z=\frac{-0.15}{0.10} \\\\ Z=-1.5[/tex]
Hence, the bag weight is 1.5 standard deviation below the mean value.
