Test the claim that for the population of statistics final exams, the mean score is $76$ using alternative hypothesis that the mean score is different from $76.$ Sample statistics include $n =17,$ $\overline{x}=78,$ and $s = 11.$ Use a significance level of $\alpha = 0.05.$ (Assume normally distributed population.)

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

A. There is sufficient evidence to reject the claim that the mean score is equal to 76.
B. There is not sufficient evidence to reject the claim that the mean score is equal to 76.
