a. Develop the appropriate hypotheses for this problem. b. Compute the test statistic. c. Compute the p-value. d. Using the p-value approach at 95% confidence, test the above hypotheses. e. Using the critical value approach at 95% confidence, test the hypotheses. ANS: a. …

For example, to find the critical value for a chi-square with 10 degrees of freedom at the 95% significance level, use row 10 and the ( = 0.05 column of the attached table (giving a value of 18.31). Alternatively, using EXCEL, one could compute CHIINV(0.05, 10) = 18.307.

Compute the test value. Compute the critical value. Use . Make a decision whether to reject or not to reject the null hypothesis. Is the test value less than the critical value? In other words, does the test statistic fall in the critical region? No, do not reject . Summarize the conclusion.

7. The critical F value with 6 numerator and 60 denominator degrees of freedom at ( = .05 is. a. 3.74. b. 2.25. c. 2.37. d. 1.96. 8. The ANOVA procedure is a statistical approach for determining whether or not. a. the means of two samples are equal. b. the means of two or more samples are equal. c. the means of more than two samples are equal

If you are working with proportions, ( Use p-value: p (Z < Zi) 3. Define the rejection area, compute the critical values (cut-off points) of the distribution, Zcritic, tcritic and define the decision rule. The most important part in a hypothesis test is to define what area under the curve is considered the area of rejection of the null hypothesis.

The critical regions are shown in Figure below. Step 3: Compute the test value. Since the standard deviation s is given in the problem, it must be squared for the formula. Step 4: Make the decision. Do not reject the null hypothesis, since the test value falls between the critical values region, as shown below. Step 5: Summarize the results.

a. Compute the test statistic. b. Using the p-value approach, test to see if there is a significant difference between the expected and the actual values. Let ( = .05. c. At 95% confidence, test for a significant difference using the critical value approach. 2.

Step 3 Compute critical values and formulate decision rule. Critical value must be t, at 0.05 level of significance and 10 degrees of freedom; n1+ n2 -2 = 5 + 7 -2 = 10. =TINV(0.05,10) = + 2.23. Decision rule: Reject the null hypothesis if t-test from the sample data is larger than 2.23 or smaller than -2.23.
