Suppоse yоu tаke independent rаndоm sаmples from populations with means μ 1 and μ 2 and standard deviations σ 1 and σ 2 . Furthermore, assume either that (i) both populations have normal distributions, (ii) the sample sizes ( n 1 and n 2 ) are large. If X 1 and X 2 are the random sample means , then, the quantity ( x ¯ 1 − x ¯ 2 ) − ( μ 1 − μ 2 ) σ 1 2 n 1 − σ 2 2 n 2 behaves like a {"version":"1.1","math":"text{Suppose you take independent random samples}\ text{from populations} text{with means}; mu_{1} ;text{and}; mu_{2}\ text{and standard deviations} ;sigma_{1}; text{and} ;sigma_{2}.\ text{Furthermore, assume either that}\ text{(i) both populations have normal distributions,}\ text{(ii) the sample sizes}(n_{1} text{and} n_{2}) text{are large.}\ text{If} X_{1}text{and} X_{2} text{are the random sample means},\ text{then, the quantity}\ frac{(bar{x}_{1}-bar{x}_{2})-(mu_{1}-mu_{2})}{sqrt{frac{sigma_{1}^{2}}{n_{1}}-frac{sigma_{2}^{2}}{n_{2}}}} text{behaves like a}"}
