can i reject the null in this multiple regession...

Hi everyone, curently on the second module of my masters and learning about multiple regression, it is blowing my mind to be honest!!

in this scenario should i reject the null hypotheses or not as one variable at the end had a high p value, any help would be hugely appreciated. thanks in advance!!

using multiple regression, the model found a medium effect size, R2 = 0.13, R2adj = 0.10. The levels of PV1 and PV2 had a significant impact on OV, F(2, 65) = 4.82, p = .011.

significant relationship between OV and Pv2, t = -2.84, df = 67, p = 0.006, model predicted that DV would decrease by -1.60 for every unit of PV1.

PV2 was not found to be a significant predictor of OV, t = 0.49, df = 67, p = .628.
