Here we are asked to use a chi-square test to investigate whether there is any relationship between PTSD and blood pressure. To do this, we take the observed frequencies - how many people have/don't have PTSD, and how many have high/low blood pressure - and use these to calculate the expected frequencies: how many we would expect in each ...
