Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6103 patients treated with this drug, 151 developed the adverse reaction of nausea. Use a 0.05 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p=0.03 H:p<0.03 O B. Họ: p#0.03 H:p=0.03 O C. Ho: p=0.03 H:p>0.03 D. Họ: p=0.03 H:p+0.03 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is -2.43. (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.)

Kenneth, a competitor in cup stacking, claims that his average stacking time is 8.2 seconds. During a practice session, Kenneth has a sample stacking time mean of 7.8 seconds based on 11 trials. At the 4% significance level, does the data provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds? Accept or reject the hypothesis given the sample data below. H0:μ=8.2 seconds; Ha:μ<8.2 seconds α=0.04 (significance level) z0=−1.75 p=0.0401 Select the correct answer below:   a. Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04.   b. Reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04.   c. Reject the null hypothesis because the value of z is negative.   d. Reject the null hypothesis because |−1.75|>0.04.   e. Do not reject the null hypothesis because |−1.75|>0.04.

Rhino viruses typically cause common colds. In a test of the effectiveness of​ echinacea, 44 of the 51 subjects treated with echinacea developed rhinovirus infections. In a placebo​ group, 97 of the 110 subjects developed rhinovirus infections. Use a 0.01 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts​ (a) through​ (c) below. a. Test the claim using a hypothesis test. Consider the first sample to be the sample of subjects treated with echinacea and the second sample to be the sample of subjects treated with a placebo. What are the null and alternative hypotheses for the hypothesis​ test?

You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly larger than 70% at a significance level of a= 0.01. According to your sample, 59 out of 77 potential voters prefer Candidate A. 1. For this study, we should use Select an answer es 2. The null and alternative hypotheses would be: Ho: 2 vselect an answer v (please enter a decimal) H:? vSelect an answer v (Please enter a decimal) nces rations 3. The test statistic- (please show your answer to 3 decimal places.) Drive 4. The p-value = (Please show your answer to 4 decimal places.) 65 5. The p-value is Select an answer Ma t Course ions 6. Based on this, we should Select an answer v the null hypothesis. 7. As such, the final conclusion is that ... O The sample data suggest that the population proportion is not significantly larger than 70% at a 0.01, so there is not sufficient evidence to conclude that the proportion of voters who prefer Candidate A is larger than 70%. O The sample data…
