A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 1088 people age 15 or older, the mean amount of time spent eating or drinking per day is 1.74 hours with a standard deviation of 0.54 hour.

The dean randomly selected 33 students who took the calculus final exam and looked at their scores on it. In this sample the mean was 80.3 and the standard deviation was 3.7. No information about the population's distribution is available. Construct a 98% confidence interval for the mean score of all students who took this exam. Round your answers to 2 places after the decimal point, if necessary. If it is not appropriate to construct a confidence interval in this situation, then enter "0" in both answer boxes below. 98% confidence interval:
