99% confidence interval contains 99% of the population. It is wider than 95% confidence. (Confidence intervals contain the mean)
I would have to go with C and D on this one.
Do 60*0.25 and that's 15. 15 tables seat 2 people. we can also confirm this by doing 15*4 which is 60 (the total amount of tables) since 25%*4=100. then we know the rest of them fit 4 and 60-15=45. Now we do (15*2) + (45*4). {one for the 2 seated tables and the other for the 4 seated ones.} 30+180=210 seats.
