A 30 B 90 C 50 D can’t tell from just this displayplease use sturge's formula to calculate class intervalRefer 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. B. 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. C. The results are inconclusive because the mean body temperature is not equal to 98.6°F while the median is approximately equal to 98.6°F. O D. The results support the…
