The margin of error is 0.97849

we are given

mean=235

so,

n=235

standard deviation =7.5

so,

\sigma=7.5

we know that

ME=2*standard error

and

SE=\frac{\sigma }{\sqrt{n} }

If confidence level is 95%, then we can multiply by 1.96

so, we can multiply by 2 to get ME

now, we can use marginal error formula

ME=\frac{2\sigma }{\sqrt{n} }

now, we can plug values

and we get

ME=\frac{2\times 7.5 }{\sqrt{235} }

ME=0.97849
