Main Question Post

In order to help out the principle at a local school, I will look in to how attendance of students throughout the year might correlate with their proficiency on the required state test.

IV-numbers of days absent in an academic year
DV-child’s score on the state test

Null Hypothesis- Absences have no affect on a child’s performance on the test
Alternative Hypothesis- The more absences a child has the lower his or her score will be on the state test.
Evaluating 25 of the students’ attendance records, n=25
df=24
alpha level .05. two tailed
critical region +-2.064
t stat-1.50

Response
It is a good research question, however I have many doubts, and some of them are
1.      How you calculated value of t statistics?
2.      I am not able to figure out any sample data or summary of sample such as mean and sample variance. Only you have mentioned n = 25!
3.      What was population mean score that you have compared for obtaining t statistic?
4.      Your null and alternate hypotheses are more of association (correlation) hypotheses. Moreover, I do not think it is related to one sample t-test.
Thanks!
