Question

Two machines, C1 and C2, are making pins which must have a diameter of 8 cm ± .01 cm or they are rejected. Dotplots of 50 pins from each machine are displayed below. They are both on the same scale.

By simply looking at the dotplots, i.e. without doing any calculations or counting, compare the distributions of the two machines:

Answer 1

C2 is more accurate in it's pin diameters. while C1 continues to fall short

Answer 2

would that be it? @TheTragicallyRomantic

Answer 3

well, you are not making any calculations or counting the pins. I would say that is a clear observation. C2has more pins in the right diameter while C1's pins continue to be smaller than standard, most will be disposed of.

Answer 4

okay what about this?
In what sense is machine C2 ‘better’ at producing pins? Justify your argument.

Answer 5

Well, C2's pins continue to be closer to the mark, while C1's pins seem to be all different diameters.

Answer 6

okay is that it? i agree with you i just want to be sure that is the full answer

Answer 7

i think we have to provide the center, shape, spread and unusual features @TheTragicallyRomantic

Answer 8

Okay, let's see, what do you find unusual about the pins?

Answer 9

for C1 they are far more spread out and away from the goal point? @TheTragicallyRomantic

Answer 10

Yes, that is unusual. it almost seems like C1 started with measurement that was too small and slowly started to measure it bigger until it got them right.

Answer 11

i think by unusual features they mean outliers @TheTragicallyRomantic

Answer 12

and what do you see that falls along those "unusual features" ?

Answer 13

@saifoo.khan @confluxepic @Nnesha can you help please?
