QuestionCoveBot:

What do you believe it is?

TETSXPREME:

idk

QuestionCoveBot:

Okay. Well.. Driver A: 12 mean deliveries 3 MAD Driver B: 15 mean deliveries 3 MAD Do you know what MAD is?

TETSXPREME:

yea it means mean-absolute-deviation

QuestionCoveBot:

Correct. Do you know how to get it?

AZ:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @QuestionCoveBot Correct. Do you know how to get it? \(\color{#0cbb34}{\text{End of Quote}}\) that's irrelevant to the question

AZ:

look at the numbers in the table @TETSXPREME Driver A has a mean number of delivery of 12 Driver B has a mean number of delivery of 15 Driver A has a MAD of 3 Driver B has a MAD of 5 look at your answer choices one by one which one is true? Compare the two numbers. Which driver has a bigger mean number of delivery? What about the MAD?

TETSXPREME:

I think its D

AZ:

oops

AZ:

I made a typo Driver A has a MAD of 3 Driver B has a MAD of 3

AZ:

look at the other answer choices the correct answer is very obvious

TETSXPREME:

so it isnt D?

AZ:

no, the MAD for driver A and B are both 3 so one of them is not less than the other

TETSXPREME:

but there is none that says that

AZ:

Let's look at A and C The mean number of deliveries for driver A is 12 The mean number of deliveries for driver B is 15 and what is the MAD for both of them?

TETSXPREME:

3

AZ:

so the MAD is 3 and what does the MAD tell us? it tells us the absolute value of how much the data varies from the mean and so what's your final answer

TETSXPREME:

for both of the?

TETSXPREME:

them*?

AZ:

look at the table in the graph both of them have a MAD of 3

TETSXPREME:

oh its C?

AZ:

yeah

TETSXPREME:

tysm

AZ:

yw
