**Transcription for Educational Website:**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 19 years and a standard deviation of 15.1 months. Complete parts (a) through (d).(a) What is the probability a male's growth plates fuse after age 21?The probability a male's growth plates fuse after age 21 is [ ] (Round to four decimal places as needed.)---**Explanation of Graphs and Diagrams:**The document does not contain any graphs or diagrams that need further explanation. There is only a textual question that involves understanding the probability distribution of growth plate fusion ages based on a given mean and standard deviation.

Given: μ = 19 years σ = 15.1 months Formula Used: Z = X-μσ

Answered: The ability to determine the age of…
