Each year, over 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 has launched studies of drugresistant gonorrhea (CDC.gov website). Of 142 cases tested in Alabama, 9 were found to be drugresistant. Of 268 cases tested in Texas, 5 were found to be drugresistant. Do these data suggest a statistically significant difference between the proportions of drugresistant cases in the two states? Use a 0.02 level of significance. What is the p-value, and what is your conclusion? Test statistic = (to 2 decimals) p-value = (to 4 decimals) Conclusion: - Select your answer - v Choose the correct option. There is a significant difference in drug resistance between the two states. Alabama has the higher drug resistance rate. - Select your answer - V Each year, over 2 million people in the United States become infected with bacteria that are resistant to antibiotics.
