Answer: Probability that the proportion of students who graduated is greater than 0.743 is P = 0.4755
Step-by-step explanation:
Given that,
Probability of freshmen entering public high schools in 2006 graduated with their class in 2010, p = 0.74
Random sample of freshman, n = 81
Utilizing central limit theorem,

So,

= P( Z > 0.0616)
= 0.4755 ⇒ probability that the proportion of students who graduated is greater than 0.743.
Average rate of growth is another way of saying slope, so you can use the slope formula, which in this case would yield (11-4)/(3.5-1.2) which is an average rate of 3.04 inches per day. Essentially, the independent variable is days, because it is the days causing growth not the growth causing days. So that means you do the last day minus first day over the final height minus initial height. Hope this helps :)
