The average waist size for teenage males is 29 inches with astandard deviation of 2 inches. If waist sizes are normallydistributed, determine the z-score of a teenage male with a33 inch waist.

The z-score of a teenage with waist size 33 inch is 2

Step-by-step explanation:

Mathematically, the z-score can be calculated using the formula;

z-score = (x - mean) / SD

where mean = 29 inches, SD = 2 inches and x = 33 inch

Plugging these values, we have

z-score = (33-29) / 2 = 4/2 = 2
