Labels on 1-gallon cans of paint usually indicate the drying time and the area that can be covered in one coat. Most brands of paint indicate that, in one coat, a gallon will cover between 350 and 500 square feet, depending on the texture of the surface to be painted. One manufacturer, however, claims that a gallon of its paint will cover 450 square feet of surface area. To test this claim, a random sample of twenty 1-gallon cans of white paint were used to paint 20 identical areas using the same kind of equipment. The sample mean and sample standard deviation are: x=445.8 and s=47.5.Test using a = .05 a) If you were the manufacturer and wanted to make sure that your claim that a gallon of its paint will cover 450 square feet of surface area. what null hypothesis and alternate hypothesis would you test? H.:. H: b) What is the test statistic and critical value? c) What conclusion can you draw?
