The NCAA requires colleges to report the graduation rates of their athletes. At one large university 70.7% of all students who entered between 1989 and 1991 graduated within 6 years. 95 of the 147 students who entered with athletic scholarships graduated. Consider these 95 as a sample of the athletes who will be admitted under present policies. Is there evidence that the percent of athletes who graduate is less than 70.7% ?
A) Explain in words what the parameter p is in this setting
B) What are the null and alternative hypotheses?
C) What is the numerical value of the sample proportion p? Of what event is the p value the probability?
D) The P-value is P= 0.053 Explain why this says there is some reason to think that graduation rates are lower among athletes than among all students.
The parameter 'p' refers to the graduation rates of athletes.
