    Just a really quick explanation question. Will give rep when I go back on my comp. I've attattched the question and the Mark scheme then below I will write what I have written. Don't know if is get the marks for where it says comment on whether these assumptios are likely to be valid. For the assumpion that says its independent I wrote that workers from companies nearby may have a similar lunchtime and quite a few may go to the same service station. And then for the uniform mean rate assumption I wrote it may not be valid as more people may go to the service station on particular days e.g. if they work part time. Each explnation is worth 1 mark so I was trying to figure what I would get out of 2. If there are better explanations please tell me as this was all I could think of.
