Questions 10-15. During one flu season, 12% of patients diagnosed with flu presented severe symptoms. During the same flu season, a new anti-flu drug was being tested. The drug was given to 526 undergraduate students with the flu and only 25 of them developed severe symptoms. Based only on this information, can you conclude that the drug is a success at 99.99% confidence level? Can you infer that the new anti-flu drug alleviate the occurrence of sever symptoms for general population? Question 12. Find the test statistics 3.72 5.12 0.12 0.05 Question 13.

During the same flu season, a new anti-flu drug was being tested. The drug was given to 526 undergraduate students with the flu and only 25 of them developed severe symptoms. Based only on this information, can you conclude that the drug is a success at 99.99% confidence level? Can you infer that the new anti-flu drug alleviate the occurrence of sever symptoms for general population? Question 14. Find the right statement. Because t < critical value, we accept H0 at 0.05% significance level. Because t > critical value, we reject H0 at 0.05% significance level. Because t > critical value, we reject H0 at 0.01% significance level. Because t < critical value, we accept H0 at 0.01% significance level.
