Solution

Set up null and alternate hypothesis as:

H0: White and blue have the same effect

Ha: White and blue do not have the same effect.

In the link given the question is almost complete.

chi square = 38.729

P<0.001

As p value is very small compared to alphe 0.01

we reject nullhypothesis.

Blue and white have difference influences.
