Question: In 2011, the mean number of hours Canadians spent commuting to and from work was 4.2 hours per week. There is concern that the rising cost of housing in Canada’s large cities is increasing commuting times. To investigate whether the mean time Canadians spend commuting each week has increased over the past 5 years, a researcher collected a simple random sample of 50 Canadian adults and surveyed them about their commute to work. He then determined that the people in his sample spend an average of 4.6 hours a week commuting, with a standard deviation 2.9 hours.   Conduct the appropriate hypothesis test using α = 0.1. Be sure to assess any necessary conditions and show all your steps.
