Project Question : Is a person's BMI related to his weight?

The two variables : BMI and weight.
Why we chose this two variables??
Firstly, to calculate a person's BMI, its important that we need the height and weight of that person. Without either the height or the weight, we are unable to calculate the BMI of that person.

To calculte BMI :
weight
-----------------------------------
Height(metres) x Height(metres)

*weight divided by height (m) multiply height (m)

Example. Tom's height is 1.70metres and weight is 63kg.

BMI :
63kg
---------------
(1.70 x 1.70)

= 21.8


What is the hypothesis?
Null hypothesis :

There is no significant relationship that a person's BMI is related to his weight.

Research hypothesis :
There is a significant relationship that a person's BMI is related to his weight.
