At the ABC grocery store there are sealed packages of tomatoes for sale. Each package of tomatoes contains 9 tomatoes. The label on the package states that the average weight of the tomatoes in the package is 100 grams. There have been many complaints against the ABC grocery chain for false labeling and this is no exception. An agent of the State's weight and measure bureau obtains a random package and measures the weight of the tomatoes. The weights are in grams: 90. 95, 100, 100, 85, 90, 95, 100, 120.
