An Internal Revenue Specialist analyzes the dollar amount of 401K contributions from 5,000 high paid employees ($100,000 or more salary per year). He knows that these contributions are normally distributed with a mean of $5,000 and a standard deviation of $2,000. What number of highly paid employees can he expect will have made contributions to their 401K less than $2,000 per year, the maximum IRA contribution
the probability that a civil court jury (6 members) will have two or more white jurors if the pool of registered voters from which jurors is selected is 20% white?
A court administrator argues that it takes 6 months (=180 days) for the average civil law suit to go to trial. An auditor checks her claim. She determines from a sample of 49 civil law suits that the average number of days is 210 with standard deviation of 20. Can the auditor prove on the basis of the sample data that the court administrator’s claim is incorrect and that the average is greater than 180 days? Show each step.
