Calculate the test statistic
State the conclusion you are entitled to draw as a result of this test.
Calculate the effect size as appropriate for the hypothesis test used.

A professor believes that psychology students study more than the average college student (after all, psychology students understand the benefits to distributed practice). To test this, the professor records the weekly study rate of a sample of 20 psychology students (M = 21.6, SD = 6.8), and compares this with the University’s data on the average of 18 hours each week a typical college student studies. What is the effect size of this difference?

Solutions

Expert Solution

1) H0 : Psychology student and college students do same study.

H1 : psychology students study more than the average college student.

2) Test Statistics = 2.368

3) P value = 0.0143

4 ) Rejection region = 1.729

5) Conclusion - Psychology students study more than the average college student. PL??
