Researchers studied the survival time of cancer patients (in months) when placed on a cancer treatment. They used three different treatments which differed in the concentrations. Below is a list of the survival times. Assume that the variances of the three groups are not equal. Are the survivorship times equal in the three groups? Which test(s) can you use to calculate your answer. Why did you choose that test? Treatments Treatment 1 Treatment 2 Treatment 3 210 150 330 180 180 300 240 180 300 210 240 420 210 240 120
