How does the value of sample variance influence the likelihood of rejecting the null hypothesis and measures and the value of Cohen’s d for a one-sample t-test? a. Larger sample variance decreases the likelihood of rejecting the null but increases value of Cohen's d b. Larger sample variance increases the likelihood of rejecting the null but decreases value of Cohen's d c. Larger sample variance decreases both the likelihood of rejecting the null and value of Cohen's d d. Larger sample variance increases both the likelihood of rejecting the null and value of Cohen's d
