Consider the following hypothesis test. a. What is your conclusion if n 1-21, s 1 2-87, n 2 26, and s 2 2 4? Use α-05 and the p-value approach. Calculate the value of the test statistic (to 2 decimals). 2.05 3 The p-value is between .02 and.05 What is your conclusion? Cannot conclude that the two population variances are different b. Repeat the test using the critical value approach. What is the rejection rule for this hypothesis test? Round...
Test the following hypotheses by using the x goodness of fit test. HO: pA = 0.40, pB = 0.40, and pc = 0.20 Ha: The population proportions are not PA 0.40, PB 0.40, and Pc-0.20 A sample of size 200 yielded 40 in category A 140 in category B, and 20 in category C. Use a 1 and test to see whether the proportions are as stated n·。 (a) Use the p-value approach. Find the value of the test statistic....
Which of the following is the correct conclusion for the hypothesis test? A. Do not reject Ho; the data do not provide sufficient evidence to conclude that x is useful for predicting y. O B. Reject Ho; the data provide sufficient evidence to conclude that x is useful for predicting y. ° C. Reject Ho, the data do not provide sufficient evidence to conclude that x is useful for predicting y. D. Do not reject Ho;the data provide sufficient evidence...

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H when the level of significance is (a) a= 0.01, (b) a 0.05, and (c) a0.10. P 0.0749 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H because the P-value, 0.0749, is greater than a=0.01 O B. Fail to reject Ho because the P-value, 0.0749, is less than a = 0.01 O C. Reject...
