A survey of 1088 adults in a country, asking "As you may know, as part of its effort to investigate terrorism, a federal government agency obtained records from larger telephone and Internet companies in order to compile telephone call logs and Internet communications. Based on what you have heard or read about the program, would you say that you approve or disapprove of this government program?" Of those surveyed, 588 said they disapprove. a. Determine and interpret the sample proportion. b. At the 10% significance level, do the data provide sufficient evidence to conclude that a majority (more than 50%) of adults in the country disapprove of this government surveillance program? a. The sample proportion is (Round to two decimal places as needed.) The sample proportion from this study is the v proportion of adults in the v that v of the government surveillance program. b. What are the hypotheses for the one-proportion z-test? Ho: p= (Type integers or decimals.) Hại p What is the test statistic? z= (Round to two decimal places as needed.) Identify the P-value The P-value is (Round to three decimal places as needed.) What is the conclusion of the hypothesis test? O A. Reject Ho; the data do not provide sufficient evidence oconclude that a majority of adults in the country disapprove of the government surveillance program. O B. Do not reject H,; the data do provide sufficient evidence to conclude that a majority of adults in the country disapprove of the government surveillance program. OC. Do not reject Ho; the data do not provide sufficient evidence conclude that a majority f adults in the country disapprove of the government surveillance program. O D. Reject Ho; the data do provide sufficient evidence to conclude that a majority of adults in the country disapprove of the government surveillance program.
