For this question, show the results "by hand" and also use R to check your work. Suppose that the 4-year graduation rate at a large, public university is 70 percent (this is the population proportion of successes). In an effort to increase graduation rates, the university randomly selected 300 incoming freshman to participate in a peer-advising program. After 4 years, 222 of these students graduated. Can you conclude that this program was a success at the 5-percent level of significance? Show your work and explain. For this question, show the results "by hand" and also use R to check your work.
