Consider the data set. 2, 3, 6, 7, 9 (a) Find the range. :l (b) Use the defining formula to compute the sample standard deviation 5. (Round your answer to two decimal places.) : (c) Use the defining formula to compute the population standard deviation 0.

Hint: Consider how much the data in the respective sets differ from the mean. 0 The data change between data sets (i) and (ii) increased the squared difference 2(X - :02 by more than data sets (ii) and (iii). 0 The data change between data sets (II) and (Ill) increased the squared difference 2(X - DZ by more than data sets (I) and (Ii). 0 The data change between data sets (i) and (ii) decreased the squared difference 21(x )2 by more than data sets (ii) and (iii). 0 none of the above Angela took a general aptitude test and scored in the 82nd percentile for aptitude in accounting.

Q i% Clayton and Timothy took different sections of Introduction to Economics. Each section had a different final exam. Timothy scored 83 out of 100 and had a percentile rank in his class of 72. Clayton scored 85 out of 100 but his percentile rank in his class was 70. Who performed better with respect to the rest of the students in the class, Clayton or Timothy? Explain your answer. 0 Clayton, since his score is higher. 0 Clayton, since his percentile score is lower. 0 Timothy, since his score Is lower. 0 Timothy, since his percentile score is higher
