Statistics

People are selected to serve on juries by randomly picking names from the list of registered voters. The average age for registered voters in the county is µ=39.7 years with a standard deviation of σ=12.4. A statistician randomly selects a sample of n=16 people who are currently serving on juries. The average age for the individuals in the sample is M=48.9 years. How likely is it to obtain a random sample of n=16 jurors with an average age greater than or equal to 48.9?
