Answer:

1.625

Explanation:

First we need to find the mean of this data set

29+32+33+28+30+30+29+33=244

Then we divide 244 by the amount of numbers in the set

244/8=30.5

Then we need to find the deviation of each number

29 | 32 | 33 | 28 | 30 | 30 | 29 | 33

1.5 | 1.5 | 2.5 | 2.5 | 0.5 | 0.5 | 1.5 | 2.5

Then we take the mean from this set of data

1.5+1.5+2.5+2.5+0.5+0.5+1.5+2.5=13

Then divide

13/8=1.625

I hope this helps :)
