olon and rectal cancer are less common in countries, like italy, that consume a mediterranean diet. the primary source of fat in the mediterranean diet is olive oil. italian researchers collected data on olive oil consumption and other diet-related information from a random sample of 1,953 patients with colon or rectal cancer and 4,154 patients admitted to the same hospitals for other, unrelated reasons. we conducted a chi-square test of independence with some of the data. here are the results. in this print-out results table, the observed count appears above the expected count in each cell. low levels of olive oil moderate levels of olive oil high levels of olive oil total colon cancer 398 404.4 397 404.2 430 416.4 1225 rectal cancer 250 240.3 241 240.2 237 247.5 728 total 2016 2015 2076 6107 chi-square test: statistic df value p-value chi-square 4 1.5515802 0.8175 what can we conclude? group of answer choices higher levels of olive oil consumption are associated with lower colon and rectal cancer rates. the association is statistically significant. there is no statistically significant association between colon and rectal cancer and consumption of olive oil. we have strong evidence that olive oil consumption and the occurrence of these types of cancer are dependent. nothing, because the conditions for use of the chi-square test are not met.
