A researcher is interested in studying the perceived life satisfaction among younger adults and hypothesizes that life satisfaction among younger adults is different than the general public. She did a pilot study and gave a life satisfaction test (known to have high reliability and validity) to nine younger adults (between 20 and 30). Scores on the measure range from 0 to 5 with 5 indicative of high life satisfaction, and 0 indicative of no life satisfaction. The collected data is: 4, 3, 3, 4, 5, 2, 2, 2, 2 ... Assuming life satisfaction of 2.5 for general public, conduct the appropriate test and answer the questions.
