What is the study's margin of error?


6.1 min


4.75 min


3.05 min


0.5 min

Answer 1

Answer:

$+/-3.05$

Step-by-step explanation:

The margin of error will be the difference divided by two with a plus and minus sign

So we have;

$29.5-23.4=6.1$

Divide by $2$

$6.1$ ÷ $2=3.05$

$=3.05$

Therefore, The margin error is therefore

$+/-3.05$
