Question

Will measured the diameter of a penny as 1.9 cm using the ruler. What is the margin of error? 1.5 cm to 2.0 cm 1.5 cm to 2.5 cm 1.85 cm to 1.95 cm 1.90 cm to 1.95 cm

Answer 1

The answer is 1.5cm to 2.0cm

Answer 2

Answer:

Hence, the margin of error is:

1.85 cm to 1.95 cm

Step-by-step explanation:

It is given that:

Will measured the diameter of a penny as 1.9 cm using the ruler.

" Now we know that the margin of error is a statistic expressing the amount of random sampling error in a survey's results "

It is an amount (usually small) that is allowed for in case of miscalculation or change of circumstances.

So here we have the margin of error to be:

1.85 cm to 1.95 cm

( since the value of change to the left and right of 19 is same and is small (it is 0.05)

i.e. 1.9-0.05=1.85 cm

and 1.9+0.05=1.95 cm ).

Margin of error is: ± 0.05.
