Two types of medication for hives are being tested to determine if there is a difference in the proportions of adult patient reactions. 20 out of a random sample of 200 adults given medication A still had hives 30 minutes after taking the medication. 12 out of another random sample of 200 adults given medication B still had hives 30 minutes after taking the medication. Test at a 1% level of significance.

Let A and B be the subscripts for medication A and medication B, respectfully. Then pA and pB are the desired population proportions. 

What is the question/claim to be tested in symbols

the hypothesis is 

Ho:

Ha:

which hypothesis matches the claim 

test objective is to reject or support 

level of significance a=.05

type of test (left, right, two-tailed)

the applicable test to be applied is           (2-sampZTEST/2-sampTTEST, 2-propZTEST)

calculate the applicable test to be applied is (2-sampZTEST/2-sampTTEST, 2-propZTEST)

calculate the applicable test statistic
z or t=

p-value= 

compare p-value to a (eg. p-value greater than or less than a)

decision (reject Ho/Failed to reject)

evidence (enough/not enough)

test objective is to (reject/support): 

conclusion:

at ____ level of significance, _____ _____ that there is a difference in the proportions of adult patients who did not react after 30 minutes to medication A and medication B.
