Question

Cans of regular soda have volumes with a mean of 12.29 oz and a standard deviation of 0.12 oz. Is it unusual for a can to contain 12.43 oz of soda? Oz (Type an integer or a decimal.) Maximum "usual" value = | | oz (Type an integer or a decimal.) Is 12.43 oz an "unusual" volume? OA. Yes, because it is between the minimum and maximum "usual" values B. Yes, because it is larger than the maximum "usual" value. ° C. D. E. F. Yes, because it is smaller than the minimum "usual" value. No, because it is smaller than the minimum "usual" value. No, because it is between the minimum and maximum "usual" values. No, because it is larger than the maximum "usual" value.

Explanation / Answer

For minimum usual value,

Z = -2

or, (X - 12.29)/0.12 = -2

or, X = -2 * 0.12 + 12.29

or, X = 12.05

For maximum usual value,

Z = 2

or, (X - 12.29)/0.12 = 2

or, X = 2 * 0.12 + 12.29

or, X = 12.53

so 12.43 is not an "unusual' volume, beacause it lies between the minimum and maximum "usual' values(12.05 < 12.43 < 12.53).

Option-E) No, because it is between the minimum and maximu "usual" values.
