The speed of nitrogen molecules in the atmosphere (at 20ºc) follows a normal distribution with a mean speed of 500 meters/second and a standard deviation of 50 meters/second. which conclusion does this information best support?

Step-by-step explanation:

Given that the speed of nitrogen molecules in the atmosphere (at 20ºC) follows a normal distribution with a mean speed of 500 meters/second and a standard deviation of 50 meters/second.

i.e. we get that 68% lie within 1 std deviation from the mean

ie 68%lie between 450 and 550

95% lie between 400 and 600 and

almost 100% lie between 350 and 650

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
