Question

the standard deviation of 100 random samples of the same size is approximated to be 0.98. what is the margin of error​

Answer 1

0.098

Explanation:

0.98/100=0.098

Answer 2

MOE= ± 0.098

Explanation:

-The margin of error is calculated using the formula:

`MOE=\pm (\sigma)/(√(n))`

#Substitute to solve for MOE:

`MOE=\pm (\sigma)/(√(n))\\\\=(0.98)/(√(100))\\\\=\pm 0.098`

Hence, the margin of error is ± 0.098
