Margin of error for a population proportion is given by = p^ + or - sqrt(p^(1 - p^)/n); where p^ = 10% = 0.1 and n = 300
margin of error = 0.1 + or - sqrt(0.1(1 - 0.1)/300) = 0.1 + or - sqrt(0.09/300) = 0.1 + or - 0.017 = 0.083 to 0.117 = 8.3% to 11.7% = 25 to 35 workers
The answer would be 4.571428.

Answer:
1500
Step-by-step explanation:
64/200 = 32/100 = 16/50 =
8/25 of 480 turtles marked
divide 480 by 8 and then multiply the quotient by 25
480/8= 60
60*25=1500
