In a test of the effectiveness of echinacea, 43 of the 48 subjects treated with echinacea developed rhinovirus infections.In a placebo group, 98 of the 112 subjects developed rhinovirus infections. Use a 0.05 significance level to test the claim that echinacea has an effect on rhinovirusinfections.

Q16 A recent study reported that a 95% confidence interval for the mean travel times to work of employees in UAE is (22 minutes, 28 minutes). The interval was computed based on a random sample of 400 employees. Which one of the following statements is the correct interpretation of this interval? We are 95% confident that mean travel times to work of the employees in the selected sample lies between 22 and 28 minutes. We are 95% confident that mean travel times to work of all employees in UAE is between 22 and 28 minutes. The probability that the mean travel times to work of all employees in UAE lies between 22 and 28 minutes is 0.95. 95% of all employees in UAE travel between 22 to 28 minutes to their work.
