The margin of error is 1.85 cm to 1.95 cm.

Step-by-step explanation:

Given:

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

We need to find the margin error.

Now, as 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.

Now, we have the margin of error to be:

1.85 cm to 1.95 cm.

As, the value of change to the left and right of 19 is same and is small it is 0.05.

So, 1.9-0.05 = 1.85 cm

and 1.9+0.05 = 1.95 cm .

Hence, the margin of error is: ± 0.05.

Therefore, the margin of error is 1.85 cm to 1.95 cm.
