You recently moved and before painting your bedroom, you were interested in testing the hypothesis that bedroom colour was related to life satisfaction. You created a poll on Instagram and surprisingly got 80 responses. You asked for the colour of people's bedrooms and whether or not they were satisfied with life. The data are provided below.

Test the hypothesis at the 5% significance level (? = 0.05) using the 5-step hypothesis testing procedure (show ALL steps). Make sure to clearly state the null and alternative hypotheses in formal symbol notation (or in words if formal symbol notation is not appropriate). Show your work. Show the formula and all steps of the calculations and not just the final answer. Round all values to 2 decimal places.
