Consider the following sample observations on stabilized
viscosity of asphalt specimens.
| 2754 | 2895 | 3006 | 2856 | 2882 |
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 = |
