Ponemon Institute, along with Intel, published “The Cost of a Lost Laptop” study in April 2009. With an increasingly mobile workforce carrying around more sensitive data on their laptops, the loss involves much more than the laptop itself. The average cost of a lost laptop based on cases from various industries is $49,246.This figure includes laptop replacement, data breach cost, lost productivity cost, and other legal and forensic costs. A separate study conducted with respect to 30 cases from health care industries produced a mean of $67,873. Assuming that σ = $25,000 is there sufficient evidence to support the claim that health care laptop replacement costs are higher in general? Use a 0.001 level of significance.
