Data Set 1 has a mean of 54 and a MAD of 4. Data Set 2 has a mean of 60 and a MAD of 2. What can you conclude about the two distributions? Choose exactly two answers that are correct. A. The means-to-MAD ratio is 3. B. The means-to-MAD ratio is 1.5. C. The distributions are similar. D. The distributions are somewhat similar.

i need help on this one, i will give medal and fan!!

OpenStudy (michele_laino):

I think that one option can be the last one, namely D, since the two distribution have the same shape approximately

OpenStudy (michele_laino):

distributions*

OpenStudy (anonymous):

i am here, sorry , bathroom break

OpenStudy (anonymous):

but it is a multiple choice

OpenStudy (anonymous):

so there must be two or more,

OpenStudy (anonymous):

mainly 2

OpenStudy (michele_laino):

ok! I try

OpenStudy (michele_laino):

I think the third option, namely C

OpenStudy (michele_laino):

for the same reasons in option D

OpenStudy (anonymous):

it must be c or d, not both, for sure

OpenStudy (anonymous):

i will check myself, hold on a sec

OpenStudy (michele_laino):

ok!

OpenStudy (anonymous):

if u think it is c, then that means that it is a as well

OpenStudy (anonymous):

i mean b, not a

OpenStudy (michele_laino):

and if I think it is d?

OpenStudy (anonymous):

u shouldnt, because it is not a as well

OpenStudy (michele_laino):

ok!

OpenStudy (anonymous):

u see, d is somewhat, and the number 1 between 2.5 is somewhat similar

OpenStudy (anonymous):

and if it is similar, then it would have to be less or equal to one

OpenStudy (anonymous):

so i know for a fact that a is not correct

OpenStudy (anonymous):

so if b is for sure correct, then it would have to be c

OpenStudy (anonymous):

done :)

OpenStudy (michele_laino):

I think that the first distribution has a width which is double of the width of the second distribution

OpenStudy (michele_laino):

so we can consider those distributions similar

OpenStudy (anonymous):

it is b and c, thx for ur help, i have one more, do u mind?

OpenStudy (anonymous):

i will post

OpenStudy (michele_laino):

ok!

OpenStudy (anonymous):

a new question, byw, thx so much fur all of ur help with me!

OpenStudy (michele_laino):

thanks!
