Answer 1

Step-by-step explanation:

5.(a)highest mark=95

     lowest mark=35

  (b)range =95

  (c)mean=(90+70+90+80+35+43+55+95+81+74)/10

               =713/10

                =71.3

6.mean=(0+1+2+3+4+5+6+7+8)/9

            =36/9

             =4

7.mode =25,20(it repeats for 2 times)

  asending order=7,8,10,12,15,16,18,19,20,20,22,23,24,25,25

median=19

therefore,mode and median are not same
