Do you write hypotheses for Pearson's Correlation coefficient?

Hey! :)
I have a maths exemplar in which the fellow wrote a rejection equation, null hypotheses, alternate hypotheses and even working at a 95% confidence for PEARSON's correlation coefficient.

This is highly unusual, because this is usually done for the chi-squared test a completely different stats test!?

Should I do it?

There shouldnt be any hypothesis for the pearson's. It's just a way to quantify the correlation in the data. Giving you a number to describe how tightly connected the data points are. The only hypothesis you could use is that they do/do not have a correlation and then the number you calculate would prove/disprove the hypothesis.
