the values are correct, I copied and pasted them separate from the photo so how do I solve the question? here is the exact question:

$3.$See how strong the relationship is $$between relational satisfaction and relational maintenance $($this $$should be $$viewed on $$a computer$).$

$$

Rel Sat Rel maintenance

$1615$

$91$

$79$

$108$

$1816$
