A random sample of n = 10 observations from a normal population produced x = 47.6 and s2 = 4.9. Test the hypothesis H0: μ = 48 against Ha: μ ≠ 48 at the 5% level of significance. State the test statistic. (Round your answer to three decimal places.) t = State the rejection region. (If the test is one-tailed, enter NONE for the unused region. Round your answers to three decimal places.) t > t < State the conclusion. H0 is rejected. There is insufficient evidence to conclude that the mean is different from 48. H0 is rejected. There is sufficient evidence to conclude that the mean different from 48. H0 is not rejected. There is sufficient evidence to conclude that the mean is different from 48. H0 is not rejected. There is insufficient evidence to conclude that the mean is different from 48.
