This assignment is associated with Chapters 11 and 12 (Salkind). Instructions: There are lots of techniques that we can use to try to calm down or relax when we are feeling anxious or tense. One strategy is deep breathing (see this link for some tips on deep breathing, https://www.uofmhealth.org/health- library/uz2255 [>). A professor is interested in examining how deep breathing can influence feelings of anxiety. She recruits participants in her class right before the final exam, when their feelings of anxiety would be high. She measures their current levels of anxiety, instructs them to engage in 2 minutes of deep breathing, and then measures their anxiety again after they've completed the breathing. Below are the anxiety levels of each student before and after deep breathing (on a scale from 1 to 15). Your job is to determine if their anxiety levels significantly DECREASE after deep breathing
