a technical supplier tests four generators by measuring their output voltages at three different instances for break-in purposes. Design a program that uses a nested loop to enter each generator's test results, and then computes and displays the mean output voltage of these equipment. Assume the following test results, Voltage Instance 2 222.5 227.0 Eapt No. Voltage Instance 1 Voltage Instance 3 1081 223.7 223.0 2061 220.2 225.1 2405 221.7 224.9 226.0 3368 222.9 223.8 226.7
