The mean GPA of night students is significantly different than the mean GPA of day students at the 0.01 significance level. Null and alternative hypothesis? H0:μN=μD H1:μN≠μD When it says "significantly different" would we choose the option with the line going through the equal sign?

The positive critical value is: How do we solve for critical value and then use this info to figure out if the hypothesis was rejected or failed? < Based on this we: Reject the null hypothesis OR Fail to reject the null hypothesis
