2. State the NULL Hypothesis or Ho 3. Identify H1 as one or two-tailed 4. Specify alpha level (level of significance) 5. Specify Degrees of Freedom (n - 1) 6. Identify Critical Value (to;) from the t table (in the appendix) 7. Calculate t-score-(tob) using SPSS (this has been done for you and the following printout shows the analysis of the data. 8. State decision (rejection) rule -use the diagram of the normal distribution curve a. If the calculated t is beyond the t crit, then the NULL is rejected b. If the calculated t not beyond the cril, then there is a FAILURE to reject the NULL State the meaning of the results, explain the outcome, and draw a conclusion. 9. Independent Samples T test Practice with SPSS We investigate the effects of sensitivity training on a policeman's effectiveness at resolving domestic disputes (comparing independent samples of policemen who had or had not completed the training). The dependent variable was their ability to successful resolve domestic disputes. The following scores were obtained: No course Course 11 13 14 16 10 14 12 17 8 11 15 14 12 15 13 18 9 12 11 11 a. What are the independent and dependent variables? b. State the null and alternative hypotheses. c. Using an alpha = 0.05, what is t (crit)? d. Using SPSS, calculate t (be) e. What should you conclude
