Assignment #5 Hypothesis Testing 1 Find the p-values for the following Zstat values use "=NORM.S.DIST(Z, TRUE) 1/2-pt Zstat = -2.45 One-Sided p-value (do you need to subtract from 1.00?) Two-Sided p-value 1/2-pt Zstat = 1.72 One-Sided p-value (do you need to subtract from 1.00?) Two-Sided p-value 2 Given: H = 170 n = 64 0 = 40 r = 183 Conduct a 2-sided test Example 1/2-pt Ho: Ho: u = 5 Ha: Ha: p # 5 1/2-pt SEr = o/Vn = Table B or use "=NORM.S.DIST(Z, TRUE) 1/2-pt Zstat = (6 - H )/SE = Is Zstat Positive? Y/N Do you need to subtract value in Table from 1.000? Y/N Is the test 2-sideded? Y/N Do you need to multiply by 2? Y/N 1/2-pt The p-value is: 1/2-pt What Significance Level is this? None, Marginal, Significant, Highly Significant? Conclusion: 1/2-pt4 Given: H = 198.8 n= should n = 10 or 2? 0 = 8.7 r = 162 You choose 1-sided or 2-sided Example Ho: = HI Ho: 1 = 5 Ha: Ha: H # 5 1/2-pt SET= o/Vn = Table B or use "=NORM.S.DIST(Z, TRUE) 1/2-pt Zstat = (6 - H )/SE = Is Zstat Positive? Y/N Do you need to subtract value in Table from 1.000? Y/N Is the test 2-sideded? Y/N Do you need to multiply by 2? Y/N 1/2-pt The p-value is: 1/2-pt What Significance Level is this? None, Marginal, Significant, Highly Significant? Conclusion: 1/2-pt Enough Evidence to Support a General Conclusion (Yes / No...Why) 1/2-pt Next Steps3 Given: H = 175 n = 39 0 = 50 r = 195 Example 1/2-pt Ho: Ho: H = 5 Ha: Ha: H # 5 1/2-pt SEr = o/Vn = Table B or use "=NORM.S.DIST(Z, TRUE) 1/2-pt Zstat = (6 - H )/SE = Is Zstat Positive?
