In a random sample of 33 car owners in Tennessee, the sample mean amount spent per year on comprehensive auto insurance was $920.35, and the sample standard deviation was $263.42. Use this data to construct a 98% confidence interval estimate for the mean amount spent per year on auto insurance by car owners in Tennessee. This confidence interval estimate should be constructed using a t-score. How many degrees of freedom will the t-distribution have in this problem? What t-score should be used to construct this 98% confidence interval? What is the lower limit for the confidence interval estimate of the mean?
