How to generate a signal with zero mean and 0.2 variance (uniform)

I was wondering how to generate this signal, and to mix it with xn that I already made:
n = [0:1023];
omega = 0.25*pi;
xn = sin(omega*n);
plot(n,xn);
I also need to find the SNR of the combined signal and plot the magnitude spectrum if possible.
