Follow the instructions given

1) In a two-tailed test with a = * 1 point 5) If the z computed value is * 1 point 0.05, the z computed value is 2.53 and the z critical value is 1.524, what is the critical 1.645, what will be your value? conclusion? +1.645 O Reject the null hypothesis. +2.575 O Do not reject the null hypothesis. O +2.436 O Reject both hypotheses. +1.960 O Do not reject both hypotheses. 2) If the rejection region is * 1 point 6) Which of the following * 1 point +1.10, what will be your alternative hypothesis is decision if the z computed illustrated if the Critical value= value is 2.34? 1.645? Reject the null hypothesis. Ha: H Ho Do not reject both hypotheses. O Ha: J = Ho 7) If the computed test * 1 point 3) If the t critical value is 1.812 * 1 point statistic is 1.87, what decision and the t computed value is can be made? Critical value: + 1.17, what will be your 1.645 decision? O Reject both hypotheses. Accept Ho Do not reject both hypotheses. O Accept Ho and Ha O Do not reject the null hypothesis. O Reject Ho Reject the null hypothesis. Reject Ha 4) If the sample size is 30, * 1 point 8) If the sample size given is * 1 point what test statistic will you 27, what is the degree of use? freedom? t - test O 24 O z - test 25 O population standard deviation O 26 O population mean O
