Each year, more than 2 million people in the United States become infected with bacteria that are resistant to antibiotics. In particular, the Centers of Disease Control and Prevention have launched studies of drug-resistant gonorrhea.† Suppose that, of 221 cases tested in a certain state, 14 were found to be drug-resistant. Suppose also that, of 322 cases tested in another state, 6 were found to be drug-resistant. Do these data suggest a statistically significant difference between the proportions of drug-resistant cases in the two states? Use a 0.02 level of significance. (Let
p
1
= the population proportion of drug-resistant cases in the first state, and let
p
2
= the population proportion of drug resistant cases in the second state.)



1) State the null and alternative hypotheses. (Enter != for ≠ as needed.)


2) What is the test statistic & P-value?


3) what is the conclusion?


A) Reject
H
0. There is a significant difference in drug resistance between the two states.


B) Reject
H
0. There is not a significant difference in drug resistance between the two states.


C) Do not reject
H
0. There is not a significant difference in drug resistance between the two states.


D) Do not reject
H
0. There is a significant difference in drug resistance between the two states.
