One manufacturer claims that a gallon of its paint will cover 400 square feet of surface area. To testthis claim, a random sample of ten 1-gallon cans of white paint were used to paint 10 identical areas usingthe same kind of equipment. The actual areas (in square feet) covered by these 10 gallons of paint are:368365310447311303412410376350Do the data present sufficient evidence to indicate that the average coverage differsfrom 400 square feet? For this test of hypothesis, H, is rejected at the 5% significancelevel
