A random sample of n = 43 observations from a quantitative population produced a mean x? = 2.9 and a standard deviation s = 0.28. Your research objective is to show that the population mean ? exceeds 2.8. Calculate the p-value for the test statistic z = 2.40. (Round your answer to four decimal places.) USE SALT p-value = You may need to use the appropriate appendix table to answer this question.

Consider using a z test to test H0: p = 0.9. Determine the P-value in each of the following situations. (Round your answers to four decimal places.) (a) Ha: p > 0.9, z = 1.47 (b) Ha: p < 0.9, z = -2.71 (c) Ha: p ≠0.9, z = -2.71 (d) Ha: p < 0.9, z = 0.27 You may need to use the appropriate table in the Appendix of Tables to answer this question.
