Reference no: EM131396983

Perform a Wilcoxon rank sum test on the following data on the length of time that it took to perform two types of operations.

For type 1, six patients were operated on in 45,47,50,53,58, and 62 minutes. In the second type of operation it took 51, 56, 60, 63, 64, 69, and 70 minutes. Use the normal approximation.
