R = 400

b)

R = 300     \ \  

c)

R = 200

2.

FIND THE MEAN OF THE GIVEN DATA.

600, 470, 170, 430, 300

a)

Mean = 300

b)

Mean = 250

c)

A.D = 127.2

b)

A.D = 105.7

c)

A.D = 217

4.

c)

21,704

5.

FIND THE STANDARD DEVIATION.

c)

S.D = 140

6.

WHICH ONE IS THE CORRECT SOLUTION OF RANGE.

600, 470, 170, 430, 300

a)

RANGE = H-L

Therefore,

R = 600-300

=300

b)

RANGE = L-H

Therefore,

R= 300-600

=-300

c)

RANGE = H + L

Therefore.

R = 600+300

= 900
