Test the claim that for the population of statistics final exams, the mean score is 74 using alternative hypothesis that the mean score is different from 74. Sample statistics include n=18,¯¯x=75, and s=11. Use a significance level of α=0.05 (Assume normally distributed population.)


The test statistic is
The positive critical value is
The negative critical value is
The conclusion is
