Question

A sample of 15, 10 years -old children was taken to study whether watching television reduces the amount of physical exercise, causing weight gains. The number of kilograms each child was overweight by was recorded (a negative number indicates the child is underweight). In addition, the number of hours of television viewing per week was also recorded. These data are listed in the table below.

Televisioin hours	42	34	25	35	37	38	31	33	19	29	38	28	29	36	18
Overweight (kg)	8	3	0	0	6	6	3	3	-4	4	4	2	1	6	-3

a. Use an appropriate plot to investigate the relationship between Television(hours) and Overweight (KG). briefly explain the selection of each variable on the X and Y axes and why?
b. Calculate and interpret the coefficient of correlation (r) between
Television(hours) and Overweight (KG).
