Why do we calculate the "range" of the measurments?

to get an ballpark idea of how much "error" is in the "average" measurement

to set upper and lower error limits on the y-value of each x-y data pair

to show if a straight "trend line" represents the experimental data

all of the above

Ascientist is working with a new kind of quantum dot to make a dye. he is applying newton’s laws to the particle, but it seems to be breaking these laws of physics. which action will most likely the scientist study the particle’s motion? a. he needs to remember that the particle is too large for quantum analysis. b. he must continue to use newtonian mechanics, but he needs to learn more about the particle. c. he needs to use quantum mechanics, not newtonian mechanics, because this is a nanotechnology product. d. he must determine new physical laws that only apply to quantum dots.
