Identify the null hypothesis, alternative hypothesis, test statistic, critical value(s), P-value (range of P-value), conclusion about the null hypothesis, and final conclusion that addresses the original claim. Assume that the two samples are independent simple random samples selected from normally distributed populations. The drug Clarinex is used to treat symptoms from allergies. In a clinical trial of this drug, 2.1% of the 1655 treated subjects experienced fatigue. Among the 1652 subjects given placebos, 1.2% experienced fatigue. Use a 0.05 significance level to test the claim that the incidence of fatigue is greater among those who use Calrinex. A) Test the claim using a hypothesis test. B) Construct an appropriate confidence interval.
