In the previous study, the hypothesis test results in a p-value less than 0.01. What is the conclusion of the study?
Solution:
Since, the p-value less than 0.01, it is concluded that reject the null hypothesis.

A hypothesis test is conducted to test the null hypothesis that the mean is less than 12. Use a 0.01 level of significance. What type of test is this? Right tail Two tail Left tail What is the critical value? 2.33 -2.33 1.78 correct answer is not given Suppose the test statistic was -2.50 What is the conclusion? Fail to reject Ho. There is not sufficent evidence to support the claim that the mean is less than 12. Reject Ho....
Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...
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...
A P-value of 0.12 is calculated on a hypothesis test with a significance level set at 0.01. Which of the following is the correct conclusion for the test? a. Claim the null hypothesis is true b. Fail to reject the null hypothesis c. Reject the null hypothesis d. Claim the alternative hypothesis is true Which of the following are not requirements for using the t-distribution for a hypothesis test concerning μ? (More than one answer may be correct.) a. Sample...
For an hypothesis test on the population proportion for the alternative hypothesis is LESS THAN, if the p-value was 0.04, what is the test statistic? A -1.751 B 1.751 C -0.516 D 0.516
The P-value is.................(Round to four decimal places as needed.) The P-value for this hypothesis test is............................(Round to three decimal places as needed.) The P-value for this hypothesis test is................................(Round to three decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is....................(Round to three decimal places as needed.) Trials in an experiment with a polygraph include 97 results that include 22 cases of wrong results and 75 cases of correct results. Use a...
Consider the following hypothesis test Ho: p 2 0.75 a' p < 0.75 A sample of 400 items was selected. Compute the p-value and state your conclusion for each of the following sample results. Use α = .05 Round your answers to four decimal places a. p=0.69 p-value Conclusion: p-value less than or equal to 0.05, reject b. p0.72 p-value Conclusion: p-value greater than 0.05, do not reject c. p=0.71 p-value Conclusion: p-value less than or equal to 0.05, reject...
The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a=0.10. P = 0.0674 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject Ho because the P-value, 0.0674, is less than a =0.01. OB. Fail to reject He because the P-value, 0.0674, is less than a =0.01. OC....
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. H0: p=0.4 versus H1: p>0.4 n = 250; x = 105, α = 0.01 Is np0 (1 - p0) ≥10? Yes No Use technology to find the P-value. P-equals=__?__ (Round to three decimal places as needed.) Reject Do not reject the null hypothesis, because the P-value is ▼ greater less than α.
The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Hy when the level of significance is (a) a = 0.01, (b) a = 0,05, and (c) < =0.10. P = 0.0998 (a) Do you reject or fail to reject Hy at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0998, is greater than a =0.01. O B. Fail to reject H, because the P-value, 0.0998, is less...
