Consider the following hypotheses:Ho: PHAP= 0.400.40A sample of size 200 was collected out of which there were 56successes. Suppose we conduct a test at the 5% significance level.a. Determine the critical values: ±315b. Calculate the test statistic: 0.00001c. Choose the correct decision and the correct reasoning:Fail to reject the null hypothesis since the test statistic fallsoutside the critical values.O Fail to reject the null hypothesis since the test statistic fallswithin the critical values.O Reject the null hypothesis since the test statistic falls outsidethe critical values.O Reject the null hypothesis since the test statistic falls within thecritical values.

The question is about hypothesis testingGiven :Selected no. of samples ( n ) = 200No. of successes…

Answered: Consider the following hypotheses: Ho:…

B. Identify the test statistic. ______ C. Identify the P-value. ____ D. What is the conclusion for this test? The P-value is (greater than/less than) the significance level α, so (reject/ fail to reject) the null hypothesis. There is (sufficient/ insufficient) evidence to support the claim that vinyl gloves have a greater virus leak rate than latex gloves.
A null hypothesis is that the average blood pressure for adult is 70. For a sample of 60 adults, the average blood pressure is 71.8. A significance test is done, and the p-value is 0.20 what is the most appropriate conclusion? A. Reject the hypothesis that the population averages 70 B. Fail to reject the hypothesis that the population averages 70 O C. Reject all hypothesis that the sample average is 70 D. None of these. E. Conclude that the population average is 71.8

Prof. Johnson conducts a hypothesis test on whether the proportion of all UBC students who bike to school (denoted as p) equals 30%. Specifically, Prof.Johnson has H0:p=0.3 versus HA:p≠0.3. He obtains a P-value of 0.01. On the other hand, Prof. Smith would like to test if there is sufficient evidence to support that p is greater than 0.3 at the 10% significance level. Based on Prof. Johnson's result, will the null hypothesis of Prof. Smith's test be rejected? A. There is insufficient information to tell.B. Yes.C. No.
If the p-value of a hypothesis test is equal to 0.035, then the null hypothesis will be rejected for which cases? SELECT ALL THAT APPLY. a. for a significance level of 0.01 b. for a significance level of 0.10 c. for a significance level of 0.05 d. for a significance level of 0.02
Next Question Assume a significance level of a = 0.05 and use the given information to cd d (b) below. Original claim: More than 43% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0443. ..... a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho.) Choose the correct answer below. A. Fail to reject Ho because the P-value is greater than x. B. Reject H, because the P-value is less than or equal to a. C. Fail to reject H, because the P-value is less than or equal to a. O D. Reject Ho because the P-value is greater than a. b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? A. There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 43%. B. There is not sufficient evidence to support the…
After performing a hypothesis test, the p-value is p = 0.013. If the test was performed at a significance level of a = 0.046, should the null hypothesis be rejected? O a. Reject the null hypothesis since 0.013 0.046 O c. Reject the null hypothesis since 0.013 > 0.046 O d. Fail to reject the null hypothesis since 0.013 < 0.046
The test statistic of z=1.54 is obtained when testing the claim that p=0.723. 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 a=0.10, should we reject H0 or should we fail to reject H0?
