1. Find if it is a one-sided test or two-sided test. 2. Find the t-test critical value. (The significance value is α = 0.08) 3. State the decision rule whether to reject or do not reject. 4. Make the conclusion with the two approaches. Step 2: One-Sample Statistics N Mean Std. Deviation Std. Error Mean Price 600 13491.88 2985.566 121.885 One-Sample Test Test Value = 13492 95% Confidence Interval of the Difference Lower Upper -239.50 239.25 Significance Mean Difference 122 t df One-Sided p Two-Sided p 599 .500 666 Price -.001 SPSS Results Step 3: Find the t-test critical value State the decision rule Reject or do not reject (there is evidence or there is no evidence)

Consider an upper tail test at the alpha = 0.01 significance level with test statistic t_test = 2.638 with degrees of freedom df = 94. a) Use the Critical Value approach to decide whether to reject H_0. b) Use the p-value approach to decide whether to reject H_0.

1. What is the critical value for z-test @0.10 using one-tailed is? z= 1.28 z=1.96 z=2.33 z=1.645 2. What is the hypothesis test should be used in this problem: Has the mortality rate reduced for lung cancer caused by smoking? one-tailed t-test two-tailed t-test one tailed z-test two-tailed z-test 3. "The results obtained from statistics analysis between the pulse rate at baseline and the pulse rate after smoking using t-test is 0.001, what should be the decision?" reject the null hypothesis do not reject the null hypothesis restate the null hypothesis no decision 4. " If the hypothesized value is outside the confidence interval estimate, the decision is to :" reject the null hypothesis do not reject the null hypothesis restate the null hypothesis no decision

Examine the following hypothesis test with n = 9, s = 10, and x̄ = 17. H₀: μ ≥ 22 Hₐ: μ < 22 α = 0.01 a. State the decision rule in terms of the critical value of the test statistic. b. State the calculated value of the test statistic. c. State the conclusion. a. State the decision rule. Select the correct choice below and fill in any answer boxes in your choice. (Round to four decimal places as needed.) A. Reject the null hypothesis if the calculated value of the test statistic, t, is greater than the critical value of ____. Otherwise, do not reject. B. Reject the null hypothesis if the calculated value of the test statistic, t, is less than the critical value of ____ or greater than the critical value of ____. Otherwise, do not reject. C. Reject the null hypothesis if the calculated value of the test statistic, t, is less than the critical value of ____. Otherwise, do not reject.
