isabelles family held a garage sale last weekend. they sold 7 items for: $8.00 $8.00 $5.00 $2.00 $4.00 $3.00 $5.00 what was the mean absolute deviation of the prices of the items? if the answer is a decimal, round it to the nearest ten cents. mean absolute deviation (mad): $

Answer

Explanation:

Step1: Calculate the mean

The sum of the prices is (8 + 8+5 + 2+4 + 3+5=35). There are (n = 7) items. The mean (\bar{x}=\frac{35}{7}=5).

Step2: Calculate the absolute - deviations

For (8): (|8 - 5|=3) (twice); for (5): (|5 - 5| = 0) (twice); for (2): (|2 - 5|=3); for (4): (|4 - 5| = 1); for (3): (|3 - 5|=2).

Step3: Calculate the sum of absolute - deviations

The sum of absolute - deviations is (3\times2+0\times2 + 3+1+2=6 + 0+3 + 1+2 = 12).

Step4: Calculate the mean absolute deviation

The mean absolute deviation (MAD=\frac{12}{7}\approx1.71). Rounding to the nearest ten - cents, (MAD = 1.70).

Answer:

(1.70)
