Question
Consider the following sample observations on stabilized viscosity of asphalt specimens.
2,797 2,907 3,008 2,836 2,881
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 a = 0.05.)
Ho: μ> 3,000
C
Ha: μ< 3,000
Ho: μ = 3,000
Ha: μ = 3,000
Ho: μ = 3,000
Ha: H = 3,000
Ho: μ< 3,000
Ha: H = 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 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 not 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.
O Do not reject the null hypothesis. There is not sufficient evidence to conclude that the true average is viscosity differs from 3000.
