Directions: Answer the following questions on a separate sheet of paper. For each problem, tse the specified approach to decide wbether to reject the null byporbesis. In cach ease, be sure to: 1) Cite your evidence a. For the p-value approach, specify the correct Excel function, write the p-value (to 4 decimals) and compare it to a b. For the Critical Value approach, look up the CV(s) and either apply the appropriate mathematical rule or draw the rejection region diagram 2) State your conclusion about the null hypothesis (i.e. Reject H0 - Do not reject H0 ) 3) State your conclusion about the aliemative hypothesis (i.e. accept HA:HA is unsupported) 1. Consider an upper tail test at the =0.05 significance level with an F test statistic of Fteit=3.28. The degrees of freedom are df1=20, and df2=10. a) Using the p-value approach, decide whether of not to reject the null hypothesis. b) Using the Critical Value approach, decide whether or not to reject the null hypothesis. 2. Consider a two-tailed test at the =0.05 significance level with an F test statistie of Fted=2.14. The degrees of freedom are df1=25, and df2=20. a) Using the p-value approach, decide whether of not to reject the null hypothesis. b) Using the Critical Valwe approach, decide whether or not to reject the null hypothesis. 3. Consider an upper tail test at the =0.01 rignificance level with an F test statistic of Ferst=1.64. The degrees of freedom are df1=30, and df2=24. a) Using the p-value approach, decide whether or not to reject the null hypothesis. b) Using the Critical Value approach, decide whether or not to reject the null hypothesis. 4. Consider a two-tailed test at the a=0.10 significance level with an F test statistic of Ftest=4.03. The degrees of freedom are df1=6, and df2=7. a) Using the p-valie approach, decide whether or not to reject the sull hypothesis. b) Using the Critical Value approach, decide whether of not to reject the null hypothesis
