Find the probability that the mean energy level is greater than 1075 kWh.

In one region, the September energy consumption levels for single-family homes are found to be normally distributed with the mean of 1050 kWh and a standard deviation of 218 kWh. If 50 different homes are randomly selected, find the possibility that their mean energy consumption level for September is greater than 1075 kWh.
