Question 27

A study of 20 students compares the time spent studying (t t\,t hours) and their final test scores (s s\,s marks).

The product moment correlation coefficient for the sample is r=0.435r = 0.435r=0.435.

Stating your hypotheses clearly test, at the 2.5% significance level, whether there is a positive correlation between study time and test scores.
