Question
The ability to determine the age of some individuals can be difficult if there are not quality government records of birth. Bone growth takes place at the growth plates at the end of long bones. Once all growth plates fuse, growth stops, and
an individual is considered a biological adult. The age at which growth plates fuse for males is approximately normally distributed with a mean of 18.7 years and a standard deviation of 16.1 months. Complete parts (a) through (d) below.
