The mean load of a fire subterranean insect specialist is 3.11 mg with a standard deviation of 0.49 mg. Allow us to expect that the heaviness of any fire subterranean insect is free from the heaviness of some other fire insect. A common fire insect settlement contains 240,000 fire insect laborers. Assume we take a gander at the heaviness of every subterranean insect in a normal fire insect province. Leave M alone the irregular variable addressing the mean load of all the laborer subterranean insects in the province in mg. Let T = the arbitrary variable addressing the amount of the loads of all the laborer insects in the province in mg.

g) What is the rough likelihood M is somewhere in the range of 3.111 and 3.112?

h) What is the rough likelihood that T is inside 2 standard deviations of its normal worth?
