One research study of illegal drug use among 12- to 17-year-olds reported a decrease in use (from 11.4% in 1997) to 9.8% now. Suppose a survey in a large high school reveals that, in a random sample of 1,056 students, 96 report using illegal drugs. Use a 0.05 significance level to test the principal's claim that illegal drug use in her school is below the current national average. Formulate the null and alternative hypotheses. Choose the correct answer below. O A. Ho: p=0.098 Ha: p>0.098 О В. Но: р30.098 H: p+0.098 ОС. Но: р<0.098 Ha: p= 0.098 O D. Hn: p=0.098 H: p<0.098 Find the test statistic. E(Round to two decimal places as needed.) z= Find the P-value for the found test statistic. (Round to four decimal places as needed.) P-value = Now make a conclusion. Choose the correct answer below. O A. Reject Ho. There is insufficient evidence to support the claim that illegal drug use in this principal's school is below the current national average. O B. Do not reject Hn. There is sufficient evidence to support the claim that illegal drug use in this principal's school is below the current national average. O C. Do not reject Hn. There is insufficient evidence to support the claim that illegal drug use in this principal's school is below the current national average. O D. Reject Hn.
