Astudent is assessing the correlation between the number of hours a plant receives sunlight in the height to which it grows. the table shows the data:

number of hours of sunlight (x) :
0 1 2 3 4 5 6 7 8 9
height of plants in cm (y) :
4 7 10 13 16 19 22 25 28 31

part a: is there any correlation between the number of hours of sunlight that a plant receives in the height to which grows?
justify your answer.

part b: write a function that best fits the data.
