For the following scenario, answer the questions below.Please note, do not conduct inference in this problem; just answer each question.

Health professionals warn that transmission of infectious diseases may occur during the traditional handshake greeting.An alternative method of greeting is the "fist bump" where two individuals touch closed fists during the greeting.Researchers compared the hygiene of each of these greetings in a study.A sterile-gloved hand was dipped into a culture of bacteria, then made contact for two seconds with another sterile-gloved hand either during a handshake or a fist bump.The researchers then counted the number of bacteria present on the second recipient's gloved hand.From a larger group of volunteers, a random sample of 32 individuals was selected and 16 handshakes were analyzed.Another random sample of 32 individuals was selected and 16 different fist bumps were analyzed. (The researchers wanted to determine if there exists a difference in mean bacteria counts between the different greetings).The data set is called "Greeting Bacteria Counts."
