Consider the following sample observations on stabilized viscosity of asphalt specimens. 2,782 2,904 2,992 2,818 2,887 USE SALT Suppose that for a particular application, it is required that true average viscosity be 3,000. Does this requirement appear to have been satisfied? State the appropriate hypotheses. (Use α = 0.05.) Ho: μ< 3,000 H₂: μ = 3,000 Ho: μ = 3,000 H₂: H = 3,000 Ho: μ = 3,000 H₂:μ # 3,000 Ho: μ> 3,000 H₂: μ< 3,000 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) t = P-value = What can you conclude? O Reject the null hypothesis. There is not sufficient evidence to conclude that the true average is viscosity differs from 3000. O Do not reject the null hypothesis. There is not sufficient evidence to conclude that the true average is viscosity differs from 3000. O Do not reject the null hypothesis. There is sufficient evidence to conclude that the true average is viscosity differs from 3000. O Reject the null hypothesis. There is sufficient evidence to conclude that the true average is viscosity differs from 3000. You may need to use the appropriate table in the Appendix of Tables to answer this question.
