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:
-5/4
Answer:
No it cannot be concluded.
Step-by-step explanation:
The probability of getting the disease in the first attempt is 50%
The probability of getting the disease in the second attempt is 50%
Thus the probability of getting the disease in either of the turns is 50%+50%=100% (which may seem to be true)
BUT
The probability of not getting the disease in the first attempt is 50%
The probability of not getting the disease in the second attempt is 50%
Thus the probability of not getting the disease in either of the turns is 50%+50%=100% (which is also true for this case)
Thus the probability of getting the disease in either of the 2 contacts is still 50%
The slope of the line is 2/3, so the angle is arctan(2/3) ≈ 33.69°.
