In Step 3 was Her Mistake

Answer:

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

How to estimate 9.1% of 59.3
gavmur [86]

Answer:

6

Step-by-step explanation:

For a quick rough estimate, I'd round 9.1% up to 10% and 59.3 to 60.  10% of 60 is 0.1(60) = 6.

For a more accurate estimate, round 9.1% down to 9% and 59.3 up to 60.  Then 9% of 60 is 5.4.
