A significance test is performed to test the null hypotheses H0: p = 0.8 versus the alternative Ha: p < 0.8. The test statistic is z = 0.9. Which of the following is closest to the P-value for this test? (A) 0.8159 (B) 0.5 (C) 0.1841 (D) 0.05 (E) Not enough information to tell. We need the degrees of freedom to determine the P-value for this significance test.

Consider a two-tailed test at the 0.05 significance level with a test statistic of Ftest = 2.14. The degrees of freedom are df1 = 25 and df2 = 20. Using the p-value approach, decide whether or not to reject the null hypothesis. Using the Critical Value approach, decide whether or not to reject the null hypothesis.
Adi S.
The one-sample t statistic from a sample of n = 26 observations for the two-sided test of H0: μ = 64 Ha: μ ≠64 has the value t = 1.12. (a) What are the degrees of freedom for t? df = ____ (b) Locate the two critical values t* from Table C that bracket t. (Enter your answers to three decimal places.) ____< t < ___ What are the two-sided P-values for these two entries? (Round your answers to three decimal places.) ____ < P-value < ____ (c) Is the value t = 1.12 significant at the 10% level? Yes/No Is it significant at the 5% level? Yes/No
