Answer 1

Step-by-step explanation:

Mean is 3+4+5+6+7/5 = 5

And 8+7+4+3+5/5 = 27/5

Answer 2

Mean, Median, Mode

X         f        fx        c.f.

3         8       24       8

4         7        28      15

5         4       20      19

6         3        18       22

7         5       35        27

       ∑f=27 ∑fx=125

mean= ∑fx/∑f

=125/27

=4.62

median:

(n+1)/2

=27+1 /2

=14

in the column of cumulative frequency (c.f.),

15 is the value just greater than 14,

and the corresponding x value of 15 is 4,

therefore,

median=4

mode:

the x value which has the highest frequency(8) is 3,

therefore,

mode=3
