The data set MaleTemps (found on the textbook website) consists of 65 body temperatures from healthy male volunteers aged 18 to 40 that were participating in vaccine trials. Put this data set into the Descriptive Statistics applet and answer the following questions.
a. Is the distribution of temperatures symmetric, skewed to the left , skewed to the right, or something else?
b. Would you think the mean temperature for the 65 males in the study is about the same as the median, higher than the median, or lower than the median? Why?
c. Find and report both the mean and median temperatures. Were you correct in your answer to the previous question?
d. Remember that the standard deviation can be described as roughly the average distance between a data value in the distribution and the mean of the distribution. Check the Guess box next to the Std dev box in the applet. You should see a box centered on the mean. Adjust the “length” of this box with your mouse so it extends as wide as what you think is one standard deviation in each direction based on the description of standard deviation given above. Now check the Show actual box for the standard deviation. What is the actual standard deviation? Where you accurate in your guess?
