We are testing H₀: ? ? 8;versus H_A: ? 8.Given ? = .01,n = 25, $\bar { X } = 8.112$ and s = .16,we should reject the H₀.(Assume the sample is selected from a normally distributed population. )

Question

We are testing H₀: ? ? 8;versus H_A: ? > 8.Given ? = .01,n = 25, $\bar { X } = 8.112$ and s = .16,we should reject the H₀.(Assume the sample is selected from a normally distributed population. )

We can calculate the test statistic as: t = (8.112 - 8) / (0.16 / sqrt(25)) = 6.75 Using a t-distribution table or a calculator, we can find the p-value to be less than 0.01, which means that the evidence against the null hypothesis is significant at the 0.01 level. Therefore, we reject H₀ in favor of H_A.
