Answer:
2.57
Explanation:
Given the data:
X : 17, 17, 16, 17, 23, 22, 21
Mean absolute deviation (MAD) :
Σ|x - xbar| ÷ n
xbar = Σx/ n
n = 7
Σx = (17 + 17 + 16 + 17 + 23 + 22 + 21) = 8
xbar = 133/7 = 19
|x - xbar| :
|17 - 19|= 2
|17 - 19| = 2
|16 - 19| = 3
|17 - 19| = 2
|23 - 19| = 4
|22 - 19| = 3
|21 - 19| = 2
Therefore,
MAD = (2+2+3+2+4+3+2) / 7
MAD = 18 / 7
MAD = 2.57
<span>Despite the fact that
China's agriculture output is the biggest on the planet, just around 15% of its
total land zone can be used to cultivate. China's arable land, which makes
about 10% of the total arable land on the planet, supports more than 20% of the
total populace.</span>

Hi, thank you for posting your question here at Brainly.
In order to answer this question, you must have data for the electricity cost. For this example let's follow the electricity cost for USA. According to U.S Energy Information Administration, the an average home costs 12.3 cents per kW-h in January 2017. For consistency, convert year to hours. In a year (365 days), there are 8769 hours.
12.3 cents/kW-h * 0.5 kW * 8769 h = 53929.35 cents = $539.2935
