Answer:
13.76ft²
Step-by-step explanation:
Side of square: d=8ft
Area of board: Sb=d×d=64ft²
Area of circle: Sc=pi×r²=pi×(d/2)²=pi×d²/4=pi×64/4= 16×pi=50.24ft²
Remainin area: Sb-Sc=64-50.24=13.76ft²
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 20 degrees of freedom, CV = 2.086.
SE = s / √n
SE = 0.16 / √21
SE = 0.035
So the margin of error is:
ME = 2.086 × 0.035
ME = 0.073
