A national college researcher reported that 65% of students who graduated from high school in 2012 enrolled in college. Twenty nine high school graduates are sampled. Round the answers to four decimal places. (a) What is the probability that exactly 17 of them enroll in college? The probability that exactly 17 of them enroll in college is
(b) What is the probability that more than 14 enroll in college? The probability that more than 14 enroll in college is .
(c) What is the probability that fewer than 11 enroll in college? The probability that fewer than 11 enroll in college is .
(d) Would it be unusual if more than 24 of them enroll in college? It (Choose one) be unusual if more than 24 of them enroll in college since the probability is .

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
