How would you test the following hypothesis:
A fast-food restaurant claims that 75% of their revenue is from the
"drive-thru". Suppose you have 50 days of receipts from the
restaurant. Each days' receipt shows the total revenue and the
"drive-thru" revenue for that day. I'm in a quandary as to how one
would conduct this test. The two revenues are obviously dependent
under the null hyp; thus it's not just a simple test of comparing two
means from independent samples.(Even if the samples were independent,
I'm not sure how to do it-because of the 75% factor in the hyp. This
is a moot point ,though, since the samples are clearly dependent to
start with)
Thanks for any help.
