In a study of 823 randomly selected medical malpractice lawsuits, it was found that 477 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed Which of the following is the hypothesis test to be conducted? OA. Ho: p=0.5 H₁: p>0.5 OC. Ho: p=0.5 H₁: p<0.5 OE. Ho: P<0.5 H₁: p=0.5 What is the test statistic? 2=0 (Round to two decimal places as needed.) What is the P-value? P-value= (Round to three decimal places as needed.). What is the conclusion about the null hypothesis? OA. Fail to reject the null hypothesis because the P-value is greater than the significance level, a B. Reject the null hypothesis because the P-value is greater than the significance level, a C. Reject the null hypothesis because the P-value is less than or equal to the significance level, a OD. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a What is the final conclusion? OA. There is not sufficient evidence to support the claim that most medical malpractice lawsuits are dropped or dismissed. B. There is sufficient evidence to support the claim that most medical malpractice lawsuits are dropped or dismissed OC. There is sufficient evidence to warrant rejection of the claim that most medical malpractice lawsuits are dropped or dismissed. D. There is not sufficient evidence to warrant rejection of the claim that most medical malpractice lawsuits are dropped or dismissed REZER B. Ho: p=0.5 H₁: p0.5 OD. Ho:p>0.5 H₁: p=0.5 OF. Ho: p0.5 H₁: p=0.5

What’s P value???

questions : "determine the null and alternative hypotheses" and the pnes below it.

Suppose that in a random selection of 100 colored candies, 24% of them are blue. The candy company claims that the percentage of blue candies is equal to 29%. Use a 0.05 significance level to test that claim. H,: p>0.29 OC. H, p=0.29 H, p#0.29 O D. Ho p+0.29 H, p=0.29 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two 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.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 29% O B. Fail to reject H. There is sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 29% O C. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to…

A. Suppose we want to test whether or not three means are equal. We want to perform this test with a 8% significance level.If we perform an ANOVA test, what is the probability of the test producing accurate results (avoiding a Type I error)? B. Suppose we, instead, run three separate hypothesis tests (t-tests), each with 8% significance level. Mean 1 = Mean 2Mean 1 = Mean 3Mean 2 = Mean 3What is the probability that all three tests would be accurate? C. Why is an ANOVA test more accurate than 3 different tests?

a. Identify the null and alternative hypotheses for this test. Choose the correct answer below. b. Identify the test statistic for this hypothesis test. c. The​ P-value for this hypothesis test is d. Identify the conclusion for this hypothesis test.

Passed Failed White Results from a civil servant exam are shown in the table to the right. Is there sufficient evidence to support the claim that the results from the test are discriminatory? Use a 0.05 significance level. 16 14 candidates Minority candidates 7 21 Determine the null and alternative hypotheses. O A. Ho: White and minority candidates do not have the same chance of passing the test. H4: White and minority candidates have the same chance of passing the test. B. Ho: A white candidate is more likely to pass the test than a minority candidate. H,:A white candidate is not more likely to pass the test than a minority candidate. Ho: A white candidate is not more likely to pass the test than a minority candidate. H,: A white candidate is more likely to pass the test than a minority candidate. D. Ho: White and minority candidates have the same chance of passing the test. H,: White and minority candidates do not have the same chance of passing the test. Determine the test…

According to a Pew Research Center study, in May 2011, 33% of all American adults had a smart phone (one which the user can use to read email and surf the Internet). A communications professor at a university believes this percentage is higher among community college students. She selects 323 community college students at random and finds that 134 of them have a smart phone. In testing the hypotheses: Ho: p= 0.33 versus Ha: p > 0.33 Do the hypothesis test. Use a level of significance of a = 0.05; Use the unrounded values in Excel to find the answers for # 3 and #4. 1. I 4. Find the p-value.-- 5. The communication professor should the null hypothesis.

a. Set up null and alternative hypotheses to try to determine whether there is a difference in ad impact between general TV viewing and VOD viewing. Conduct the hypothesis test defined in (a), using the 0.05 level of significance.
