Suppose that scores on the quantitative SAT exam among students inNY public universities who are taking Calculus I have approximately a normal distribution with mean 580 and s.d. 80.[a]What proportion of such students scored above 720?[b]What are the quartiles of these scores?[c]Suppose there are 35 students in a particular section of Calculus I at NYU and the mean QSAT score for these students is 634 with a s.d. of 94. Treat this class as a random sample of students at NYU who take this course and construct a 95% confidence interval for the mean QSAT. How does the mean at NYU compare to the mean for all such students in NY?
