A store that sells LPG claims that the mean weight of their mini-tanks are exactiy 6-kgs as prescribed. Using a random sample of 15 mini LPG tanks, a regular customer tests the theory that the average weight of the store's tanks are somehow lower than the prescribed weight. Use a significance level of a=0.10 5.78 5.98 6.01 6.09 6.23 5.89 6.00 6.03 6.10 6.24 5.92 6.00 6.05 6.15 6.25
