As part of my new university course I am taking I need to do some statistics so I decided to do some practice. As I said I am new to statistics and I am currently very stuck on the following question:
And so far I have handled the question like this but I am not sure if I am doing it properly..
i)
Mon - ($150+140+110=400$)
Tue – ($70+80+65=215$)
Wed – ($20+18+21=59$)
Thu – ($25+22+16=63$)
Fri - ($35+30+35=100$)
$$\text{Total} = 400+215+59+63+100 = 837$$ $$p(Mon) = 400/837 = 0.47\%$$
ii)
$$\text{Ananova}/\text{Tuesday} = 70/(70+80+65)=70/215= 0.32%$$
iii)
No clue.
iv)
Didn't get to it. But cant really think of a way how to distribute the values using Bayes law.
The questions a bit weird but it would be lovely if someone can help me out on this issue.
