A survey was administered to 27 psychology students at Langara. We surveyed the following questions

Rated from 1-7. 1= Strongly disagree, 4= neither agree nor disagree, 7=strongly agree

Happy: "In general, I consider myself a happy person": x= 3.3, s=1.5

Satistfied: "In general, I am satisfied with my life": x= 4.7, s=1.2

Belong: "Do you feel a sense of belonging here at Langara"

Extraversion: "Do you consider yourself an introvert or an extravert"

First, let us explore our class's perceptions of well-being on the following survey questions: In general, I consider myself a happy person (happy), and I am satisfied with my life (satisfied). One way to understand our class means would be to compare them to another sample or to a specific population. Instead, we are going to compare them to a specific numerical standard. Do PSYC students, on average, significantly agree or disagree with these statements? In other words, is our class mean significantly different from the scale midpoint of 4, which indicates "neither agree nor disagree"? Conduct the appropriate hypothesis test using alpha = .05, 2 tailed.

1- State the null and research hypotheses using scientific notation. These hypotheses will be the same for both survey questions. [1 point]

2- Conduct one-sample t test for the happy and satisfied survey questions. Calculate cohen's D and the 95%CI. Report the results APAstyle. You can include both survey questions in 1paragraph. Include all descriptive statistics. Note: for t-test we can not calculate the exact p-value by hand, but you can report whether it is greater or less than your alpha (ie p<.05 or p>.05). Remember that APA follows this format: t(df)=X.XX, p=.xx, d=X.XX, 95CI [x.xx, x.xx]
