The data below represents the number of students in 10 7th grade classes.
20, 18, 21, 18, 22, 24, 18, 23, 23, 24

a. What is the median of the data:

b. What number of students describe the first quartile (mean of lower quartile):

c. What number of students describe the third quartile (mean of upper quartile):

d. What number of students describe the interquartile range (third quartile - first quartile):

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

i dont know sorry

step-by-step explanation:

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
