dude:

Okay first off, do you know how to read this?

Kaihalojr:

yes, I looked at the key

dude:

Okay what makes you think its B?

Kaihalojr:

okay, I don't really think it's b any more

Kaihalojr:

but I think that it might be D because I think each time there is another number like 11 to 14 i think that's a new day with a new amount of emails on that day.

dude:

B was saying that the average is 8 If we find the average of all the emails \(\large \frac{8+8+9+11+11+14+16+17+18+18+21+23+30+30}{14}\approx 16.7\) 8 is not the average We see from the plot that the highest number is 30, so it is D

Kaihalojr:

Thank you

dude:

np :)

Kaihalojr:

B- not bad dat was my fault though :I

dude:

Oh what happened?

Kaihalojr:

dude:

Kaihalojr:

I'm not that surprised honestly it's a unit test I didn't expect a perfect score
