1. what relationship do you notice between age and height?

Explanation:

To match the people with the numbers on the graph, we assume that the numbers on the graph correspond to the people from left - to - right.

1. Alice is the first person on the left, so she is number 7.
2. Brenda is the second person, so she is number 6.
3. Cathy is already given as 3.
4. Dennis is the fourth person, so he is number 1.
5. Errol is the fifth person, so he is number 2.
6. Freda is the sixth person, so she is number 5.
7. Gavin is already given as 4.

For the relationship between age and height (assuming the vertical axis is age and the horizontal axis is height), as height increases, age also tends to increase. So, there is a positive correlation between age and height.

Answer:

1. Alice – 7, Brenda – 6, Cathy – 3, Dennis – 1, Errol – 2, Freda – 5, Gavin – 4
2. There is a positive correlation between age and height.
