Consider the following random sample observations on stabilized viscosity of asphalt specimens. 2083 2027 2003 1817 2017 suppose that for a particular application, it is required that true average viscosity be 2000. is there evidence this requirement is not satisfied? from previous findings we know that the population standard deviation, σ = 90.5. state the appropriate hypotheses. (use α = 0. calculate the sample mean and standard error. (round your answers to three decimal places)
