In 2010, the mean expenditure for auto insurance in a certain state was $806.  An insurance salesperson in this state believes that the mean expenditure for auto insurance is less today.  She obtains a simple random sample of 32 auto insurance policies and determines the mean expenditure to be $781 with a standard deviation of $39.13.  Is there enough evidence to support the claim that the mean expenditure for auto insurance is less than the 2010 amount at the α = 0.05 level of significance?
