The test statistic of z=1.19 is obtained when testing the claim that p>0.4. a. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. b. Find the​ P-value. c. Using a significance level of α=0.01​, should we reject H0 or should we fail to reject H0​?

Consider the following two confidence intervals for B₁: 90% confidence interval: [0.49, 29.51] 95% confidence interval: [-2.29, 32.29] You want to test the null hypothesis that B₁ = 0 against the alternative hypothesis that ß₁ ‡ 0. Which of the following is true? Select all that apply. You reject the null hypothesis at the 5% significance level You fail to reject the null hypothesis at the 10% significance level. You fail to reject the null hypothesis at the 5% significance level You reject the null hypothesis at the 10% significance level

Test the daim that the proportion of men who own cats is significan tly different than the proportion of women who own cats at the 0.02 significance level. The null and alternative hypothesis would be: Ho:PM = PF Ho:HM PF Ho:PM µp H1:µM PF H1:µM + HF The test is left-tailed two-tailed right-tailed Based on a sample of 80 men, 40% owned cats Based on a sample of 20 women, 50% owned cats positive Critical Value = [three decimal accuracy] Test Statistic = [three decimal accuracy] Based on this we: O Reject the null hypothesis O Fail to reject the null hypothesis

Use the given information to find the p-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). K The test statistic in a right-tailed test is z=0.52. OA. 0.6030; fail to reject the null hypothesis OB. 0.0195; reject the null hypothesis OC. 0.3015; reject the null hypothesis OD. 0.3015; fail to reject the null hypothesis I Z 7 s 7 S x H command E D с III T R F G B Y I H U N B I J M G K O 6 H Time Remaining: 01:02:48 P command E . ? option Next

Use a t-test to test the claim about the population mean u at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: u+ 29; a = 0.10 Sample statistics: x =30.3 , s 5.2, n = 11 What are the null and alternative hypotheses? Choose the correct answer below. A. H u#29 H u= 29 B. H: uz 29 H u 29 VD. H,: H= 29 H: u#29 correct: 0 What is the value of the standardized test statistic? The standardized test statistic is (Round to two decimal places as needed.)

A two-tailed hypothesis test is being used to evaluate a treatment effect with α = .05. If the sample data produce a z-score of z = 1.65, then what is the correct decision?​ Select one: a. Fail to reject the null hypothesis and conclude that the treatment has no effect. b. Fail to reject the null hypothesis and conclude that the treatment has an effect. c. Reject the null hypothesis and conclude that the treatment has an effect. d. Reject the null hypothesis and conclude that the treatment has no effect.

The test statistic of z=2.26 is obtained when testing the claim that p≠0.659. a. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. b. Find the​ P-value. c. Using a significance level of α=0.01​, should we reject H0 or should we fail to reject H0​?

Use the given information to find the ​p-value. ​Also, use a 0.05 significance level and state the conclusion about the null hypothesis​ (reject the null hypothesis or fail to reject the null​ hypothesis).   With H1​: p≠​0.377, the test statistic is z=3.06.

The test statistic of z=2.75 is obtained when testing the claim that p≠0.317.   a. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. b. Find the​ P-value. c. Using a significance level of α=0.10​, should we reject H0 or should we fail to reject H0​?

The test statistic of z=2.53 is obtained when testing the claim that pnot ≠0.469.   a. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. b. Find the​ P-value. c. Using a significance level of α=0.10​, should we reject Upper H (sub)0or should we fail to reject Upper H (sub)0​?
