2 answers:
Answer:
<h2>Cameron solution is not reasonable, because it must have 4 decimals points, not three.</h2>Step-by-step explanation:
When calculating the area of the rectangular wall, we have to multiply 16.5ft(8.625ft), if we observe, we have 4 decimals in total. The multiplications results 142.3125. So, Cameron solution is not reasonable, because he only included three decimals points, instead of four.

Answer:
24.2(to the nearest tenth)
Step-by-step explanation:
The question is ungrouped data type
standard deviation =√ [∑ (x-μ)² / n]
mean (μ)=∑x/n
=
=33.3
x-μ for data 5, 5, 6, 12, 13, 26, 37, 49, 51, 56, 56, 84 will be
-28.3, -28.3, -27.3, -21.3, -7.3, 3.7, 15.7,17.7, 22.7,22.7,50.7
(x-μ)² will be 800.89, 800.89,745.29,453.69,53.29,13.69,246.49,313.29,515.29,515.29,2570.49
∑ (x-μ)² will be = 7028.59
standard deviation = √(7028.59 / 12)
=24.2
