Answer #1

This kind of problem can be solved using the chi-square test of independence. One can check if the height of a person and the weight of a person are dependent or independent.

For this test height and weight would be put in buckets and the groups will be compared

Null hypothesis: the two variables height and weight are independent.

Alternate hypothesis: the two variables height and weight are dependent.

Another way to obtain the regression line between the weight and height of a person and check for the significance of the slope of the regression line.

Null hypothesis: the true value of beta or slope of the regression line of height and weight is 0.

Alternate hypothesis: the true value of beta or slope of the regression line of height and weight is not 0.
