Statistician randomly chooses a sample of n=16 people who are presently serving on juries. Average age for individuals in the sample is M=48.9 years.

a) How probable is it to get a random sample of n=16 jurors with average age greater than or equal to 48.9?

b) Is it sensible to conclude that this set of n=16 people is not representative random sample of registered voters?
