A laboratory investigator interested in the relationship between diet and the development of tumors divided 90 rats into three groups and fed them with low-fat, saturated-fat, and unsaturated-fat diets, respectively. The rats were all the same age and species and were in similar physical condition. An identical amount of tumor cells was injected into a foot pad of each rat. The tumor-free time is the time from injection of tumor cells to the time that a tumor develops. All 30 rats in the unsaturated-fat diet group developed tumors; tumor-free times (in days) were the following: {112, 68, 84, 109, 153, 143, 60, 70, 98, 164, 63, 63, 77, 91, 91, 66, 70, 77, 63, 66, 66, 94, 101, 105, 108, 112, 115, 126, 161, and 178). Match Column A with possible answers in Column B. Use JASP to calculate the asked descriptive measures.
