2. 4

3. 45

4. i. 3/10

4. ii. 1/10

Step-by-step explanation:

1. mean=sum of observations/no. of observations

=1.2+3.1+2.4+4.1+1.4+3.5+2.2+1.5/8

=19.4/8

=2.425

2. Range=Largest observation-smallest observation

=7-3

=4

3. Median=Middle number when arranged in ascending or descending order

let's do this in ascending order

it will be 34, 40, 44, 45, 45, 57, 60, 70

=45

4. i. 9/9+7+11+3

=9/30

=3/10

4. ii. 3/9+7+11+3

=3/10

=1/10
