A college states that the mean number of kilometres per day that students travel for classes is 4.0. A study is done each year to verify the statement. The study for 2018 was done in the fall semester. The results were: 4, 4, 3, 2, 6, 8, 7, 1, 9, 3, 1, and 6. At the 0.05 level, can we conclude that the mean number of kilometres travelled is greater than 4.0? Determine or estimate the p-value.
