During boot camp, a drill sergeant measured the weight of the men in his unit. He found the weight roughly followed a normal distribution, given by y=0.0235e^(-(x-154)^2)/578) where x is the weight of a recruit in pounds( this is a Gaussian Model). Use a graphing calculator to sketch the function and find the average weight of the men. Sketch the graph on this grid using the following domain (100≤x≤225). Explain how you get the average. knowing what kind of graph, fix the "window" so it fits on the viewing screen of calculator.

i plugged the equation into my calculator and it sayd over flow. i have no idea how to fix the window. please help me solve this.

... you need to research what a normal distribution curve tells you about the data in question.
