An important quality characteristic of interest in a teabag filling process is the weight of the tea in the individual bags. The weight of the teabags should be as consistent as possible. In the past, the standard deviation of the weight of the teabags has been 0.05 grams. The file Teabags2 contains an ordered array of the weight, in grams, of a sample of 20 tea bags produced during an eight-hour shift. Is there evidence that the standard deviation of the amount of tea per bag is greater than 0.05 grams? (Use α = 0.01.)
