I need help with a final question on my stats homework. This is how the homework starts out, and I am given a table of data:

The Education Testing Service set out to test the relationship between two versions of an aptitude test.

Given the data, I determined the correlation coefficient to be .9276, and the coefficient of determination to be .8604. Given that this is two-tailed, using the 0.05 level of significance (with degrees of freedom at 5), the critical r value is .754.

From this, I determined that the calculated r value exceeds the critical r value.

My teacher's notes (and this chapter in my book) doesn't talk about a null hypothesis at all, but I have to determine which of these two answers is correct (note-I had 5 answers to choose from, but narrowed it down to these two):

1) "The calculated r value exceeds the critical value and thereforewe can reject the null hypothesisand conclude that the correlation coefficient is significantly greater than zero."

2) "The calculated r value exceeds the critical value and thereforewe can not reject the null hypothesisand conclude that the correlation coefficient is significantly greater than zero."

I am confused as to how I can determine what the null hypothesis is given that they only stated "The Education Testing Service set out to test the relationship between 2 versions of an aptitude test."

I really appreciate anyone who could explain this to me. It is important to me that I understand this as well! Thank you in advance.
