(aspirin) (vitamin c) (Aspirin) (Larger)
(vitamin C) (aspirin) (vitamin C) (smaller)
3)
a. This is a (two tailed) (right tailed) (left tailed) test.
2)
Rejection of the claim about aspirin is more serious because the wrong aspirin dosage could cause more serious adverse reactions than a wrong vitamin C dosage. It would be wise to use a different significance level for testing the claim about the aspirin.
3)
Alpha = 0.05
Null and Alternate Hypothesis
H0: p = 0.157
Ha: p <> 0.157
a)
This is a two-tailed test.
b)
Test Statistic
z = 1.78
P(z>|1.78|) =2*P(z<-1.78) = 2* 0.0375 = 0.075
Result
Since the p-value is greater than 0.05, we fail to reject the null hypothesis.
c)
Option A: Fail to Reject H0. There is not sufficient evidence to support the claim that p <> 0.157
