Statistics Investigative Task 1 Driver Deaths You work for a life insurance company. Your boss has assigned you the task of reviewing recent records concerning vehicle size and driver death rate. Your boss wants to know if the type of automobile a client drives should impact the cost of his or her life insurance policy. You found the status report published on June 9, 2011 by the Insurance Institute for Highway Safety for driver deaths. Rates are driver deaths per million registered vehicles. The rates below have already been adjusted with additional information (driver age, gender, and vehicle density) obtained from the Highway Loss Data Institute. Write a report to your boss including: o appropriate comparative plots and summary statistics; o descriptions of the driver death ratings for each group of automobiles; o a comparison of driver death ratings for the three sizes of automobiles; o your recommendation to your boss about your company's insurance policies.
