Figure 18.7 is from a study to examine the associations between hospital volume (number of procedures in a year, for example) and outcomes, following cholecystectomy. Low volume is 244 cholecystectomies per year. The null hypothesis is that there is no relationship between each of the outcomes shown and hospital volume. Do you think that there is enough evidence to support the hypothesis of no relationship between each of the outcomes and hospital volume?
