Second question on each exam will be to show your calculator to the web camera. Handheld calculators may be used but may only be a simple/scientific calculator. Use of a cellphone calculator, or graphing calculator will result  will be considered cheating with a “0” given for that exam/assignment. If you are unsure of the calculator you have being correct, please contact me through Canvas Messaging.  If you prefer the onscreen calculator it will be at the top of the screen for use.  Type handheld ( and show your calculator) or onscreen in the blank.

This figure shows graphed medical research results from a study on a new vaccine. The research was done in an effort to determine if a new vaccine would be effective in preventing potentially dangerous rotavirus infections in infants. Green data bars represent occurrence of infant cases that had normal rotavirus strains that aren’t critically dangerous. Blue data bars represent occurrence of infant cases that had more dangerous rotavirus strains that can hospitalize or lead to fatality of infants.  In this diagram, the Y-axis of the graph shows values of “Incidence of Illness” in infants. Thevarying numbers of infants getting sick with rotavirus represents the:
