A milk processing company test implemented a plant-wide energy conservation program with a goal of reducing the mean daily consumption rate of at least 1,000 kWh from its normal operating plants. The conservation program was implemented in Plant B. The following data was collected on weekdays where consumption level is at its peak. Were the conservation efforts effective in achieving its goal? Compare the results with Plant A's data where the program is not implemented using a = 0.05. Assume that the population variances are not equal.

Caselet #3 DAILY ENERGY CONSUMPTION
A milk processing company test implemented a plant-wide energy conservation program with a goal of reducing the mean daily
consumption rate of at least 1,000 kWh from its normal operating plants. The conservation program was implemented in Plant
B. The following data was collected on weekdays where consumption level is at its peak. Were the conservation efforts effective
in achieving its goal? Compare the results with Plant A's data where the program is not implemented using a = 0.05. Assume
that the population variances are not equal.
