Shortly after september 11th 2001, a researcher wanted to determine if the proportion of females that favored war with iraq was significantly different from the proportion of males that favored war with iraq. in a sample of 70 females, 28 favored war with iraq. in a sample of 66 males, 36 favored war with iraq.

( sorry my answer is short they wont let me do just war so ignore this) xd

part a. there were 250 teenagers surveyed (100% of tenagers = 250)therefore 1 % = 250/100 = 2.5 76% = 1% x 76 = 2.5 x 76 = 190 teenagers of the 250 surveyed liked burgerspart b: jane surveyed 25% (which is equal to 50 teenagers, i.e. a quarter of the teenagers surveyed is 50) to get 100% we simply get 4 quarters, i.e. multiply 50 by 4 = 200 teenagers were surveyed by jane. part c: it is impossible to give an example where a percentage is greater than 100%, since, by definition , percentage means "per 100".
