5) A researcher would like to know if there is a difference in SAT scores between brothers. A random sample of 15 pairs of brothers was taken and their SAT scores were obtained. Which test should be used to determine if there is a mean difference in SAT scores?

e) none of the above because the measure of angle cba is 101°

school a:

minimum value is 2

maximum value is 22

the lower quartile is 2.5

the median is 10

the upper quartile is 15.5

school b:

minimum value is 9

maximum value is 20

the lower quartile is 12

the median is 16

the upper quartile is 18

box plot for school a isn't symmetrical. the data tails on the right

box plot for school b isn't symmetrical. the data tails on the left
