Rin incorrectly calculated the mean absolute deviation for the data set 25,25,31,36,38.her work is shown here. 1. find the mean. mean = 25 + 25 + 31 + 36 + 38 5 = 155 5 = 31 2. find each absolute deviation. absolute deviations: 6,6,0,5,7 3. find the mean absolute deviation. mad = 6 + 0 + 5 + 7 4 = 18 4 = 4.5 in which step did rin make an error?

Rin did mistake in 3rd step

Step-by-step explanation:

Mean is correct  according to rin's calculation

Absolute mean deviation is  |data value-mean|

Hence, values of absolute deviations are also correct

To find the Mean absolute deviation we sum the differences of absolute deviations and then divide by the number of observations

it should be 6+6+0+7+5=24/5=4.8

Not 18/4

Hence, Rin did mistake in 3rd step

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
