Document Summary
Suppose we wanted to determine the proportion of our class that owns a netflix account. If i surveyed all 209 students in this class, and i found that 182 own a netflix account this would mean that that the proportion p of people who own a netflix account is: p= x/n. X = # of ppl in population that possess this characteristic. Suppose that a random sample of size n is obtained from a population in which each individual either does or doesnt have a certain characteristic. The sample proportion, denoted (cid:1868) is given by: characteristic. The sample proportion, (cid:1868) , is a statistic that estimates the where x is the number of individuals in the sample with the specified (cid:1868) = population proportion, p. Example 1: a survey was conducted at walker complex in brock university to determine if students were travelling outside of the country on their reading week in february.
