Alexander found the means-to-mad ratio of two data sets to be 3.4.

what can he conclude about the distributions?

a.
they are similar.

b.
they are somewhat similar.

c.
they are different.

d.
they are identical.

It is given that ratio of  Means to Mean absolute deviation(MAD) of two data sets are 3.4.

Mean is sum of all the observation divided by number of observation.

MAD can be calculated by

1. Find the mean of the data set.

2. Subtract each value of data set from the mean,and take the modulus value.

3. Find the mean of new data set.

Now, consider the  two data sets.

A={2,4,6,8,10}

B={6.8,13.6,20.4,27.2,34}

The two data set , have ratio of means to MAD is equal to 3.4.

Which shows, that two data set are different.

Option (C) : They are different is true.

step-by-step explanation:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
