Answer 1

Answer:

Sum of numbers =7+4+3+5+6+3+3+2+4+3+4+3+3+4+4+3+2+2+4+3

=104

Total numbers are 30

mean=

30

104

=3.46667=3.47

The mode is the number which appeared most.

Therefore, mode=3

For median arrange the numbers in ascending order:

1,2,2,2,2,3,3,3,3,3,3,3,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,6,7
