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 = 182/ 209. The sample proportion, denoted ^", is given by: ^ = x/ n, where x" is the number of individuals in the sample with the specified characteristic. The sample proportion, ^", is a statistic that estimates the population proportion, p". X" is the number of people in the population that possess this characteristic. 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. Of 200 students surveyed, 68 indicated that they were traveling outside of the country on reading week.
