Use the fact that the mean of a geometric distribution is μ = 1/p and the variance is σ2 = q/p2.

A company assumes that 0.5% of the paychecks for a year were calculated incorrectly. The company has 200 employees that examines the payroll records from one month.

  • Find the mean, variance, and standard deviation.
  • How many employees payroll records would you expect to examine before finding one with an error?
