Identifying Unusual Values with the Range Rule of Thumb. In Exercises,use the range rule of thumb to determine whether a value is unusual.

Volumes of Coke Based on Data Set 19, cans of regular Coke have volumes with a mean of 12.19 oz and a standard deviation of 0.11 oz. Is it unusual for a can to contain 11.9 oz of Coke? Explain.

Answer :

Step 1 of 1 :

Volumes of Coke Based on Data Set 19, cans of regular Coke have volumes with a mean of 12.19 oz and a standard deviation of 0.11 oz.

We know that mean μ = 12.19 and standard deviation σ = 0.11

According to the range rule of thumb, most values should lie within 2 standard deviations of the mean.

We can therefore identify “unusual” values by determining if they lie outside these limits:

Maximum usual value = μ + 2σ

Maximum usual value = 12.19 + 2(0.11)

Maximum...
