Question: Global TV news, in a segment on the price of gasoline, reported that the mean price nationwide is $1.29 per litre for regular unleaded gasoline. A random sample of 36 stations in Toronto revealed a mean price of $1.315 per litre and a sample standard deviation of $0.05 per litre. At the 5 percent level of significance, test the null hypothesis that gasoline prices in Toronto are no higher than the national average against the alternative hypothesis that they are.
