Refer to the data set of body temperatures in degrees Fahrenheit given in the accompanying table and use software or a calculator to find the mean and median. Do the results support or contradict the common belief that the mean body temperature is 98.6°F? Click the icon for the body temperature data. The mean of the data set is °F. (Round to two decimal places as needed.) The median of the data set is °F. (Type an integer or a decimal. Do not round.) Do the results support or contradict the common belief that the mean body temperature is 98.6°F? O A. The results contradict the belief that the mean body temperature is 98.6°F because both the mean and the median are less than 98.6°F. OB. The results are inconclusive because the median body temperature is not equal to 98.6°F while the mean is approximately equal to 98.6°F.
