hi, i am doing homework for my stat class and i am stuck on this one question. could you guys show me step by step how to solve this problem? the question is

Dr. Steven Wasserman, Dr. Philip Mackowiak, and Dr. Myron Levine of the University of Maryland conducted research on the body temperatures of healthy human adults. Fifty of the body temperatures taken from randomly selected subjects are provided below. Form a 98% confidence interval for the true average body temperature for all healthy adults, interpret the results. Does the interval contradict the belief that 98.6 is the average healthy body temperature, explain? Construct a hypothesis test also to determine if the status quo belief that the average healthy human body temp is 98.6 can be rejected using this data. Are the results from both methods consistent?

98.6 98.6 98.0 97.3 97.2

98.6 98.8 98.3 97.6 98.4

98.0 98.6 98.5 98.2 98.6

98.0 97.0 97.3 99.6 98.2

99.0 97.0 98.7 98.7 98.0

98.4 98.8 97.4 99.4 97.8

98.4 97.6 98.9 98.2 98.0

98.4 97.7 98.6 98.0 98.4

98.4 98.8 99.5 98.6 98.6

98.6 98.0 97.5 98.6 98.6

thank you
