Answer:
C.
They are different.
Step-by-step explanation:
Given that Alexander found the means-to-MAD ratio of two data sets to be 3.4.
Data set I has mean / mean absolute deviation as 3.4 times the data set II.
That is why the ratio = 3.4
This implies that the two data sets have different variations, and as a result different entries
They cannot be identical because ratio is not 1.
They cannot be similar as mad is higher for I data set
The only conclusion is option
C) they are different
