According to the Employee Benefit Research Institute (www.ebri.org), 34% of workers between the ages of 35 and 44 owned a 401(k)–type retirement plan in 2002. Suppose a recent survey was conducted by the Atlanta Chamber of Commerce to determine the rate of 35- to 44-year-old working adults in the Atlanta metropolitan area who owned 401(k)–type retirement plans. The results of the survey can be found in the file Atlanta Retirement. Based on the survey results, can the Atlanta Chamber of Commerce conclude that the participation rate for 35- to 44-year-old working adults in Atlanta is higher than the 2002 national rate? Conduct your analysis at the 0.025 level of significance. |
