Labels on 3.79 litre (L) 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, 3.79 L will cover between 23.2 and 46.4 square metres (m2), depending on the texture of the surface to be painted. One manufacturer, however, claims that 3.79 L of its paint will cover 37.2 m of surface area. To test this claim, a random sample of ten 3.79 L cans of white paint were used to paint ten identical areas using the same kind of equipment. The actual areas (in m) covered by these 3.79 L of paint are given here:

Do the data present sufficient evidence to indicate that the average coverage differs from 37.2 m? Find the p-value for the test, and use it to evaluate the statistical signifi- cance of the results.
