1.  5 , 8 , 10 , 20 , 25 , 30 , 35 , 40 , 45
     The answer is c. 25

2. upper quartile / the highest value = 30 , 35 , 40 , 45
     35 + 40 / 2 = 37.5
     The answer is b. 37.5

3. lower quartile / the lowest value = 5 , 8 , 10 , 20
    8 + 10 / 2 = 9
    The answer is c. 9

4. The answer is b. they are created by first writing a data set in order from least        to greatest

5.  The answer is c. left at 2 ; right at 7
