The sample proportion of returns with errors at the two tax offices will be 0.1389 and 0.0927 respectively.
<h3>How to calculate the sample proportion?</h3>
From the information, the the observed frequencies showing the number of sampled returns with errors and the number of sampled returns were given.
The sample proportion will be:
P1 = 35/(35 + 217)
= 35/252
= 0.1389
P2 = 28/(28 + 274)
= 28/302
= 0.0927

Here mark the angles
- m<FHG=75
- m<FGH=55
- m<GHI=59°
- m<GIH=63°
By using angle sum property
So
- m<FGH < m<IGH <m<GHI <m<GIH <m <FHG
So
Volume of a cone formula: V = πr²*h/3
V = volume
r = radius
h = height
Solve with the given values.
V = π(7)²*19/3
V = π(49)*19/3
V = 153.86*19/3
V = 974.94...
Round to the nearest one.
974.94... → 975.0
Therefore, the answer is 975.0yd³
Best of Luck!
