Below is the a set of temperatures measured in degrees fahrenheit of randomly selected normal/healthy adults. using excel, find the mean and standard deviation for the group of data for parts a and b. 98.698.698.099.098.498.498.498.798. 998.897.698.399.0a. the mean body temperature is : b. the standard deviation of the body temperatures is: c. assuming body temperature is normally distributed, what is the range (low to high) of body temperatures for the middle 68% of normal and healthy adults?
