9.2 Set the null and alternative hypotheses. Use two-sided alternative hypothesis for each. Example a) Ho: µ µ = 10 Ho: µ = 5 1/2-pt Ha: µ µ ≠ 10 Ha: µ ≠ 5 b) Ho: µ µ = 8 1/2-pt Ha: µ µ > 8 c) Ho: µ µ = 1 1/2-pt Ha: µ µ < 1 9.6 One-Sided p-value 0.957284 (do you need to subtract from 1.00?) 1/2-pt Two-Sided p-value 0.0854 9.10 Given: µ = 1.3 n = 25 σ = 0.3 1.4 1/2-pt Ho: µ µ = 1.3 Ha: µ µ ≠ 1.3 1/2-pt σ/√n = 0.06 Table B 1-pt Zstat = 1.67 ======> 0.9525 Is Zstat Positive? Y Y/N Do you need to subtract value in Table from 1.000? Y Y/N Is the test 2-sided? Y Y/N Do you need to multiply by 2? Y Y/N 1/2-pt The p-value is: 0.0949 1/2-pt What Significance Level is this? None None, Marginal, Significant, Highly Significant? ject the Ho? Therefore, do you reject Ho or accept Ha? And is there a difference?) 1-pt There is not enough evidence to reject the Ho since the p-value is greater than 0.05. There is a difference between the mean and the population mean. 9.16 Given: µ = 175 n = 39 σ = 50 195 Chapter #9:  Exercises 9.2, 9.6, 9.10, 9.16   = SE  = (  - µ )/SE =  =
