To eat "Cai Fan" or not to eat "Cai Fan". That is the question..

I was going to have lunch with Judy and the rest but there didn't seem to have anything much to eat. So I was pacing up and down on what to eat. So I thought maybe just join the rest. Then when I stood behind Judy, she asked me this very silly question, "Why you eat 'cai fan'?" ("cai fan" = economy food, vegetable rice for direct translation). I was stunned for the next 1 min, it was like asking why is the sky blue or why do I wear black today. So I told her that we need to use a statistical analysis for this and she INSISTED in seeing. So... here it is...

We want to know whether me, thinking whether to eat "cai fan", before I bought food and after is the same AND eventually decide to buy it. So while pacing up and down, I ask myself the question, "Should I eat 'cai fan'?" For more illustration, see the table below:

I was lazy to type the workings so look below for my scribbled workings hope you can see it clearly:

X-sq = 0

At α = 0.05 level, we reject H0 if X-sq > X-sq 1,0.95.
Since X-sq is less than 3.84, we do not reject H0 and conclude that I would be eating "cai fan" after all...

BUT..... Actually I just went to Bambinos to eat baked Pasta... Hahaha... Enjoy people...

Enjoying his time now
