All freshmen at Success University take an orientation class. The professors plan on taking an SRS of \[70\] of the \[800\] freshmen and asking them twice whether they agree with the statement, "If I struggle with my homework, I can find help," once before the class and once after. They plan to look at the difference \[(\text{after} - \text{before})\] between the proportions of freshmen who agree with the statement. Suppose that before the class, \[30\%\] of the freshmen agree, while after the class, \[85\%\] agree.
