The question is incomplete: the table and the answer choices are missing.
This is the table:
House 1 2 3 4 5 6 7 8
<span>
Size 1025 1288 2344 988 12,985 1500 1077 2455
</span>
These are the answer choices:
<span>
A) maximum
B) mean
C) median
D) range
</span>
Answer: option C) median.
Explanation:
You have to calculate or analyze every statistics before and after.
A) Máximun.
Before correcting the error, the maximum was 12,985 (the measure of the house 5).
After correcting the error, the new maximum is 17,985 (the corrected measure of house 5). So, this changed 17,985 - 12,985 = 5,000 (square feet).
B) Mean
<span>Increase in the mean = change in the measure / number of houses = 5,000 / 8 = 625 square feet

</span>Since, the error only modified the maximum value, the median did not change.
With the error and without the error it is the average of the two central measures: [1288 + 1500] / 2 = 1,394 square feet.
Then, this measure did not change, and this is the right answer.
D) Range:
The range is the difference between the maximum and the minimum data.
Since, the maximum data changed, the range changed.
The answer is C.92 because 10x3 is 30,8x4 is 32,and 6x5 is 30 so the equation is 30+32+30
<span>66 / 0.11 = 600 Therefore, 66 is 11 percent of 600.</span>
