Participant	Height	Weight
Participant 1	70	160
Participant 2	69	164
Participant 3	61	134
Participant 4	66	155

-Plot the scatterplot to show the relationship between height and weight, label the value for each participant.

-Base on the scatterplot, describe the relationship between height and weight (form, direction, strength, possible outlier)?

-Calculate the correlation coefficients. Does it confirm your judgment in the previous question?
