A survey was conducted with a large group of teenagers from 6 different states and it asked them for their favourite sport out of a large list of sports. The study aims to look at whether a teenager's state of residence is associated with their sporting preferences. Assume that p is the proportion of teenagers who selected the sport most preferred in their state of residence, such that p1 is that for State 1, p2 is that for State 2 and so on. Required:
Determine the chi square test association.

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
