Refer to the indicated data set in Appendix B. Use computer software or a calculator to find the

means and

medians.

a)  Body Temperatures
Use the body temperatures for 12:00 AM on day 2 from Data Set 2 in Appendix B. Do the results support or contradict the common belief that the mean body temperature is 98.6°F?

b) How Long Is a 3/4 in. Screw?
Use the listed lengths of the machine screws from Data Set 19 in Appendix B. The screws are supposed to have a length of 3/4 in. Do the results indicate that the specified length is correct?

c) Home Voltage
Refer to Data Set 13 in Appendix B. Compare the means and medians from the three different sets of measured voltage levels.

d) Movies
Refer to Data Set 9 in Appendix B and consider the gross amounts from two different categories of movies: Movies with R ratings and movies with ratings of PG or PG-13. Do the results appear to support a claim that R-rated movies have greater gross amounts because they appeal to larger audiences than movies rated PG or PG-13?
