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.

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

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.
