How I know that I don't have a mathematical mind
An informal poll of residents in a particular street indicated that four fifths of them oppose the construction of traffic lights at the end of the street. One of the residents decides to carry out a formal survey and randomly samples 20 people who live in the street. Assuming the figures obtained in the initial poll is correct, find the probability that : (a) exactly 16 residents (b) 16 or more residents oppose the construction of the lights.Now why were these people opposing the construction?
What would their manner of response to a survey be?
What petty arguments would arise at a meeting of these townsfolk?
Is statistical evidence a substantial expression of people's sentiments?
Should a decision thus be based on the poll or is a centrally made decision more representative of the people's interest?
Ok the last 2 were really pushing it....but the point is....
I thought of at least the first 3, before or at the same time as the need to figure out how to calculate the probability. My tutor just laughed. I am still trying to do SL stats. try try try. I will figure sl math out.
