1. An auditor for a medical insurance company selects a random sample of  prescription drug claims for evaluation of correct payment by company  experts. The claims were selected at random from a database of 500,000  claims by using uniform random numbers between 1 and 500,000. To  verify that the random numbers really were from a uniform distribution, the  auditor calculated the mean and standard deviation of the random  numbers. What should the mean and standard deviation be if these were  uniformly distributed random integers?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
