Question: The annual report to the stockholders of J&J Sugar Refineries stated that the average American consumes 100 pounds of sugar per year. In response to the report the North American Physicians Association conducted a yearlong study to measure the sugar consumption of 35 randomly selected people. The sample mean was 95 pounds. Assuming the sugar consumption is normally distributed with a standard deviation of 4, do the results from this sample refute the company's annual report at the 5% level of significance?
