Below is 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.

Data: 98.6, 98.6, 98.0, 99.0, 98.4, 98.4, 98.4, 98.7, 98.9, 98.8, 97.6, 98.3, 99.0

a. 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?

Answer :

the anwser is c because 68 is normal for adults sus

Final answer:

To find the mean and standard deviation of the given set of temperatures, use Microsoft Excel. The mean is 98.3 degrees Fahrenheit and the standard deviation is 0.234 degrees Fahrenheit. The range of body temperatures for the middle 68% of normal and healthy adults is approximately 98.066 to 98.534 degrees Fahrenheit.

Explanation:

To find the mean and standard deviation for the given set of temperatures, we can use Microsoft Excel.

Step 1: Enter the temperatures into a column in Excel.

Step 2: Use the AVERAGE function to find the mean of the temperatures.

Step 3: Use the STDEV.S function to find the standard deviation of the temperatures.

For part a, the mean body temperature is: 98.3 degrees Fahrenheit. For part b, the standard deviation of the body temperatures is: 0.234 degrees Fahrenheit.

For part c, assuming body temperature is normally distributed, the range (low to high) of body temperatures for the middle 68% of normal and healthy adults can be determined using the mean and standard deviation. The range is approximately 98.066 to 98.534 degrees Fahrenheit.
