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 proportion of adults in the that of the government surveillance program. b. What are the hypotheses for the one-proportion z-test? Ho: p= Ha:p (Type integers or decimals.) What is the test…
In 1998, as an advertising campaign, the Nabisco Company announced a "1000 Chips Challenge," claiming that every 18-ounce bag of their Chips Ahoy! cookies contained at least 1000 chocolate chips. Dedicated statistics students at the Air Force Academy (no kidding) purchased some randomly selected bags of cookies and counted the chocolate chips. Some of their data are given below. Complete parts (a) through (c) below. 1270 1244 a) Check the assumptions and conditions for inference. Check the data for independence. Choose the correct answer below. A. 0+ 900 1356 1132 Chips 1600 OA. The sample is less than 10% of the population, so one can assume that the data are independent. B.
