Answer:
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.
