Be sure to use the data in this exercise and not the preloaded data when using the web app. a. Define the parameter of interest and set up hypotheses to test that the proportion opposing fracking is different from 50%. Define the parameter of interest. Choose the correct answer below. A. p= the proportion of people in the country that think fracking is becoming more controversial B. p = the proportion of people in the country who oppose fracking OC. =the average number of people in the country that oppose fracking D. = the standard deviation of the number of people in the country that oppose fracking Set up the hypotheses for the hypothesis test. Ho Ha (Type integers or decimals. Do not round.) b. Of the 1,505 respondents in the survey, 734 indicated that they oppose fracking. Find the test statistic and interpret it. Select the correct choice below and fill in the answer box to complete your choice. (Round to two decimal places as needed.) OA. The test statistic is z= OB. The test statistic is z = which represents the difference between the sample estimate and the null hypothesis value. which represents the number of standard errors that the estimate falls from the null hypothesis value. c. Report and interpret the P-value. Indicate your decision, in the context of this survey, using a 0.05 significance level. P-value= (Round to three decimal places as needed.)
