Please explain the answer. The question is in the image below, thank you.

A nurse informaticist was asked to report on the influence of medication adherence on the frequency of hospitalizations among patients with a primary diagnosis of heart failure. Controlling for age and previous hospitalization rates, the nurse calculated an ordinary least squares regression of all patients meeting the criteria. The regression analysis results are provided below: Regression statistic: F=1.23, p value=0.4721 Medication adherence rating coefficient: -1.8441; 95% confidence interval (CI) -2.0145 to -1.3224 Age coefficient: 1.6521; 95% confidence interval (CI) 1.2326 to 1.8891 Previous hospitalizations coefficient: 0.4632; 95% confidence interval (CI) 0.3705 to 0.8753 Which statement is correct for the results? The regression is significant, but medication adherence has no significant effect on frequency of hospitalization. The regression is not significant. The findings could all occur by chance. The regression is significant, and medication adherence has a significant effect on frequency of hospitalization. The regression is significant and shows that improving the medication adherence rating by one point reduces the number of hospitalizations by nearly two days
