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

Answer:
Step-by-step explanation:
Sn = a1 * (r^n - 1) / (r-1)
a3 = a1r^2 = 4, and
a1 = 16 , so:
r^2 = 4/16 = 0.25
r = 0.5
S6 = 16 * (0.5^6 - 1) / (-0.5)
= 16 * 1.96875
= 31.5.
