You conduct a hypothesis test about a population mean p at a significance level of a = 0.10 using a sample of size n = 38. The population standarddeviation o is known, so you use the standardized test statistic (z). Your test statistic follows a standard normal distribution when the null hypothesisis true, and its value obtained from the sample is 2 = -2.65.Use the Distributions tool to help you answer the questions that follow.t DistributionDegrees of Freedom=60AAA-3.0-2.0-1.00.01.02.03.0 If you perform a left-tail test, the p-value isless than the significance level.If you perform a two-tail test, the p-value isgreater than the significance level.You do not reject the null hypothesis in this case, because the p-value isYourejectthe null hypothesis in this case, because the p-value is

It is more difficult to reject a null hypothesis if we use a 10% level of significance compared with a 5% level of significance. True or False
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) a = 0.10. P=0.0212 (a) Do you reject or fail to reject H, at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0212, is greater than a= 0.01. O B. Reject H, because the P-value, 0.0212, is greater than a = 0.01. OC. Reject H, because the P-value, 0.0212, is less than a = 0.01. O D. Fail to reject H, because the P-value, 0.0212, is less than a = 0.01. (b) Do you reject or fail to reject H, at the 0.05 level of significance? O A. Fail to reject H, because the P-value, 0.0212, is greater than a= 0.05. O B. Reject H, because the P-value, 0.0212, is greater than a = 0.05. OC. Fail to reject H, because the P-value, 0.0212, is less than a = 0.05. O D. Reject H, because the P-value, 0.0212, is less than a = 0.05. (c) Do you reject or fail to reject H, at the 0.10 level of significance? O A. Reject H, because…
In a(n) ________ test, the null hypothesis should be rejected when the test value is in either of the two critical regions. Explain.
In conducting a significance test, is it easier or harder to reject the null hypothesis when it's a two-tailed test instead of a one-tailed test? A: easier B: harder
Classify the hypothesis test as two-tailed, left-tailed, or right-tailed. At one school, the average amount of time that tenth-graders spend watching television each week is 20.1 hours. The principal introduces a campaign to encourage the students to watch less television. One year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased from the previous mean of 20.1 hours.
Gender and College Students: According to the U.S. Department of Education, approximately 57% of students attending colleges in the U.S. are female. A statistics student is curious whether this is true at her college. She tests the hypotheses H0: p = 0.57 versus Ha: p ≠ 0.57. She plans to use a significance level of 0.05. She calculates her test statistic to be 1.42. Using the applet, which is the P‑value?

For example, let's say that I have the following null hypothesis: "The population mean is equal to 5", and the alternative hypothesis: "The population mean is not equal to five". Then, I collect a sample from the population and after performing the hypothesis test I conclude at the 0.01 significance level: "Reject the null hypothesis", or in plain English "There is enough evidence to reject the claim that the population mean is equal to five". Then, am I proving that the population mean is not equal to five?
how do I explain the following? 1. Explain p-value In hypothesis testing , why can’t the null hypothesis be proved true? 2. Explain SignificanceExplain what is meant by a significant difference.
