A sales representative who is on the road visiting clients thinks that, on average, he drives the same distance each day of the week. He keeps track of his driving distance for several weeks and discovers that he averages 122 kilometres on Mondays, 203 kilometres on Tuesdays, 176 kilometres on Wednesdays, 181 kilometres on Thursdays, and 108 kilometres on Fridays. He wonders if this evidence contradicts his belief in a uniform distribution of kilometres across the days of the week. Is it appropriate to test his hypothesis using the chi-square goodness-of-fit test? Explain.
