Answer:
The ages of people entering a pie eating contest are normally distributed with a mean of 35 years and a standard deviation of 8.2 years.
What is the age of a pie eating contestant with a z-score of −2.1 ?
[ Age - 35 ] / [ 8.2] = -2.1 multiply both sides by 8.2
Age - 35 = -17.22 add 35 to both sides
Age ≈ 17.8 years
