Use this information to answer the next four questions The National Collegiate Athletic Association (NCAA) requires colleges to report the graduation rates of their athletes. At one large university, 78% of all students who entered in 2010 graduated within six years. In a random sample of 190 student athletes in this university, 137 graduated within six years. Is there sufficient evidence to believe that the proportion of athletes who graduate within six years is less than 78%? Use α-.05. 34....
Suppose National Collegiate Athletic Association [NCAA] rules state all student-athletes are to receive an average of 50 hours of academic support, per term. A random sample of 49 University of Maryland student-athletes revealed a mean of 47.5 hours of academic support per term. If the calculated value for the associated test statistic equaled -1.75, what was the standard deviation of the number of hours of academic support the student-athletes in the sample received per term?
23.26 Do our athletes graduate? Return to the study in Exercise 22.19 (page 530), which found that 149 of 190 athletes admitted to a large university graduated within 6 years. This did not differ significantly (P=0.0968) from the 82% graduation rate for all students at the university. It may be more informative to give a 95% confidence interval for the graduation rate of athletes. Construct this confidence interval. Is the 82% graduation rate for all students included in your confidence...
