Answer 1

See Explanation Below

Explanation:

The question is incomplete as the table is missing.

I'll give you a guide to solve questions that look like this.

To calculate the Range of an observation, you only need the highest and the lowest values.

I.e Range = Highest Value - Lowest Value.

Suppose that the table is as follows

Observation --- Time

1 ------ 1:07

2 ------- 1:00

3 ------- 1;11

4 -------- 1:05

5 -------- 1:01

The highest and the least values in the above observation are

1;11 and 1:00 respectively.

Hence, the range is calculated as;

Range = Highest - Lowest

Range = 1:11 - 1:00

Range = 11 seconds
