Problem 6. The set (Z19 − {0}, ·19) is a group with the indicated operation; see the attached table. a.) Show that H = {1, 7, 8, 11, 12, 18} is a subgroup. b.) List all the right cosets of H. c.) Show that if Hy = Hx then xy−1 ∈ H. [Make sure to give a reason for each step.] d.) Show that φ : H → Hx defined by φ(h) = hx is one-to-one and onto. [Use the fact that H is a group and the property of inverses to do this. Part (c) may also come in handy.] e.) Show that the operation ⊗ defined by (Ha) ⊗ (Hb) ≡ Hab is well-defined.

Are all disciplines in the University equally boring or there are some more boring than others? To answer that question, a study performed at Columbia University counted the number of times per 5-minute interval when professors from three different departments said “uh” or “ah” during lectures to fill gaps between words. These counts were used as a proxy (approximation) for the measure of class boredom. The data from observing one hundred of 5-minute intervals from each of three departments’ professors were recorded in...
Problem 3 Professor Bell suspected that there might be a relationship between shyness and loneliness. For 40 participants he measured shyness using the Ottawa Shyness Questionnaire and measured loneliness using the Carleton Loneliness scale. For both measures, a higher value indicates more shyness or more loneliness. The data are on the right. Did he find support for his hypothesis? Person Shyness Loneliness 1 12 6 2 6 8 3 4 8 4 13 7 5 7 5 6 13 7...
