The dot plot shows a random sample of the number of fish caught and released by 30 participants during a two-day fishing derby.

Answer 1

The average of each day is 6 fishes

Explanation:

Given

See attachment for dot plot

Required

Determine the true statement

For day 1, we have:

`Fis hes = 3 + 6 + 6 + 6 + 6 + 3`

`Fis hes = 30`

`Participants = 6`

The mean is:

`Mean = (Fish es)/(Participants)`

`Mean = (30)/(6)`

`Mean = 5`

For day 2, we have:

`Fis hes = 3 + 3 + 4 + 6 + 7 + 7`

`Fis hes = 30`

`Participants = 6`

The mean is:

`Mean = (Fish es)/(Participants)`

`Mean = (30)/(6)`

`Mean = 5`
