Name: BA 3400: Worksheet #3 Directions: For each problem, use the specified approach to decide whether or not to reject the null hypothesis. In each case, be sure to: 1) Cite your evidence a. For the p-value approach, write the p-value and compare it to \alpha b. For the Critical Value approach, look up the CV(s) and either apply the appropriate mathematical rule (see the table in Step 3 of Ch 9: Handout #2, Part One) or draw the rejection region diagram. 2) State your conclusion about the null hypothesis (i.e. reject Ho; do not reject Ho) 3) State your conclusion about the alternative hypothesis (ie. accept HA; HA is unsupported) 1. Consider a lower tail test at the a = 0.10 significance level with test statistic Zest = -1.19. a) Use the Critical Value approach to decide whether to reject Ho- b) Use the p-value approach to decide whether to reject Ho- sibility: Investigate
