All of the following increase the magnitude of the t statistic and/or the likelihood of rejecting H₀ EXCEPT A) a greater difference between the sample mean and the population mean. B) an increase in sample size. C) a decrease in sample variance. D) a smaller significance level ( a ).

Quizplus · Accepted Answer

A smaller significance level (a) actually decreases the likelihood of rejecting H₀, as it requires a stronger level of evidence to reject the null hypothesis. The other options (a greater difference between sample mean and population mean, an increase in sample size, and a decrease in sample variance) all increase the magnitude of the t statistic and/or the likelihood of rejecting H₀.
