The drug clarinex is used to treat symptoms from allergies. in a clinical trial of this drug, 2% of the 1650 treated subjects experienced fatigue. among the 1600 subjects given placebos, 1% experienced fatigue. use a .05 significance level to test the claim that the incidence of fatigue is greater among those who use clarinex.

Claim is False that the incidence of fatigue is greater among those who use Clarinex.

Step-by-step explanation:

Let and be the probabilities of the the incidence of fatigue of those using Clarinex. and placebos respectively

2% of the 1650 treated subjects experienced fatigue who are using Drug Clarinex.

= 1650

Among the 1600 subjects given placebos, 1% experienced fatigue.

= 1600

Claim : The incidence of fatigue is greater among those who use Clarinex.

We will use Comparing Two Proportions

Formula of test statistic :

Substitute the values  

test statistic :

test statistic :2.344

refer z table for p value  

p value = 0.9904

α = 0.05

Since p value >α

So, we accept the null hypothesis

So, the claim is wrong that the incidence of fatigue is greater among those who use Clarinex.
