In a sample of 50 museum visitors one afternoon, 22 were female and 28 were male. If there were 800 museum visitors that afternoon, estimate the number of visitors who were female.

It's 352 females and how to find that is you put 22/50 for the females out of the total people there and x/800 for x being the number of females you dont know then you just multiply 22 and 800 and divide by 50 which gets you 352
