Answer:
±3%
Step-by-step explanation:
A voter polling research group determined that between 40% and 46% of the voting population would vote for the republican candidate on elections day. What was the margin of error for this research?
the frange as given is 40% and 46%
40 +46=86
the middle value is 86/2
43%
43-40=3
43-46=-3
the margin of error for this research will therefore be ±3%
