A researcher is interested in studying the perceived life satisfaction among younger adults is significantly 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 data are presented below. Assume that life satisfaction for general public is 2.5, conduct the appropriate test and provide the following information:

-What significance level do you choose for this test?

A. Level of significance = 2%

B. Level of significance = 1

C. Level of significance = 95%

D. Level of significance = 99%

E. None of the above

2.What is your t critical value (calculated t value)?

A. -1.6

B. +1.3

C. +2.1

D. +1.8

Assuming p-value of 0.21 and level of significance of 0.02, interpret outcome of your analysis. Is there a significant difference of life satisfaction between young adults and general public?

A. Yes

B. No

C. Depends on sample standard deviation

D. None of the above
