Consider the following sample observations on stabilized viscosity of asphalt specimens.
2751 2899 3009 2852 2871
Suppose that for a particular application, it is required that true average viscosity be 3000. Does this requirement appear to have been satisfied? State the appropriate hypotheses. (Use = 0.05.)
Test the appropriate hypotheses. (Round your answers to three decimal places.)
test statistic t =
critical value t = ±
