Consider the table, showing the official mean weight and estimated standard deviation for five U.S. coins. Suppose a vending machine is designed to reject all coins with weights more than 1 standard deviation

above or below the mean.

Coin	Weight (grams)	Estimated standard deviation (grams)
Cent	2.500	0.06
Nickel	5.000	0.09
Dime	2.268	0.01
Quarter	5.670	0.07
Half dollar	11.340	0.12

For each coin, find the range of weights that are acceptable to the vending machine. Complete the table below.

Coin	Range of weight (grams)
Cent
Nickel
Dime
Quarter
Half dollar
	(Round to three decimal places as needed.)
