Question: There is a proposal to raise funds to build schools. Part of the money raised will be used to build schools in the city in two subdivisions (A, B).
To assess the feasibility of the proposal, asked a group of 50 people from A and 100 from B.
38 people of the A subdivision agreed with the proposal and 65 of B agreed also.
What is the probability of obtaining this minor difference or if it is believed that the proportions are the same?
