Consider the sample observations on stabilized viscosity of asphalt specimens: 2781, 2900, 3013, 2856, and 2888. Assume they come from a normal distribution. Suppose that for a particular application it is required that the true mean viscosity be less than 3000. Does this requirement appear to have been satisfied? State and test the appropriate hypotheses. Use a level of significance α=0.05, and all the three testing approaches. State your decision and conclusion
