Tonya V The commute distances at a huge corporation vary from employee to employee. It is known that the population of all these employee commute distances is approximately normally distributed. The corporation claims that the standard deviation of this population is 3.57 km. You are a recruiter who wants to test this claim with a random sample of 41 employees. Based on your sample, follow the steps below to construct a 95% confidence interval for the population standard deviation of all the employee commute distances. Then state whether the confidence interval you construct contradicts the corporation's claim. (If necessary, consult a list of formulas.)
