Description: QUESTION 1The Centers of Disease Control and Prevention has launched studies of drug-resistant gonorrhea, Of 110 cases tested in Alabama, 14 were found to be drug-resistant. Of 95 cases in Texas, 7 were found to be drug-resistant. Does the data indi

For the first city, Sample size, n1 = 110 Sample proportion, p^1=14/110 = 0.13 For the second city, Sample size, n2 = 95 Sample proportion, p^2= 7/95 = 0.07 To test the claim, that number of drug-resistant cases in the first city is higher than the second, the hypothesis of interest is H0: p1 - p2 = 0 H1: p1 - p2 > 0 Under the null hypothesis, the test statistic is Z=p^1-p^2P^(1-P^)1n1+1n2~N(0,1), P^=X1+X2n1+n2=14+7110+95=0.1024 =0.13 - 0.070.1024×0.89761110+195 = 1.41509 For the right tailed test, p-value = P(Z≥1.415)=0.0785 > α=0.005 Answers: None of the given options is correct. Conclusion: Since the p-value is greater than the given level of significance, it is not significant at α=0.005, hence the proportion of drug-resistant cases is almost the same in the two cities at the given level of significance.

The Centers of Disease Control and Prevention has launched studies of drug-resistant gonorrhea. Of 110 cases tested in Alabama, 14 were found to be drug- resistant. Of 95 cases in Texas, 7 were found to be drug-resistant. Does the data indicate that the proportion of drug-resistant cases in Alabama is higher than proportion of cases in Texas at a-.005? For the hypothesis stated above, what is the test statistic (in terms of "Alabama" minus "Texas")?
