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 (after – 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.
Consider the formula:
PA (1 - PA
Орд-ро ту
NA
PB (1 - PE
NB
Why is it not appropriate for the professors to use this formula for the standard deviation of the distribution of
the difference in sample proportions?

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after 2 hours of driving after her coffee break, her distance from her house was 210 miles. her average speed during the whole trip was 60 miles per hour. valerie created the equation y−210=60(x−2) to represent this situation, where xx represents the time in hours from her coffee break and yy represents the distance in miles from her house. which graph correctly represents valerie's distance from her house after her coffee break?
