I have the following interval 1.339-13.833

I know that the sample size is 128.

I know that the way to calculate a two-tailed confidence interval is

sample mean +/- Z(alpha/2) * s/sqrt(n)

If I put in

1.330=xbar - z (.05/2) * s/sqrt (128)

13.833 = xbar + z (.05/2) * s/sqrt (128)

How do I solve for mean and sd at the same time?

Is this problem even solvable?

Thanks!
