Given values:
![\bar{x_1}=7.1\\\\\bar{x_2}=8.3\\\\s_1=1.7\\\\s_2=1.9\\\\n_1=50\\\\n_2=39](https://tex.z-dn.net/?f=%5Cbar%7Bx_1%7D%3D7.1%5C%5C%5C%5C%5Cbar%7Bx_2%7D%3D8.3%5C%5C%5C%5Cs_1%3D1.7%5C%5C%5C%5Cs_2%3D1.9%5C%5C%5C%5Cn_1%3D50%5C%5C%5C%5Cn_2%3D39)
Using formula:
![\to (\bar{x_1} -\bar{x_2}) \pm t \sqrt{\frac{(s_1)^2}{n_1}+\frac{(s_1)^2}{n_2}} \\\\](https://tex.z-dn.net/?f=%5Cto%20%28%5Cbar%7Bx_1%7D%20-%5Cbar%7Bx_2%7D%29%20%5Cpm%20t%20%5Csqrt%7B%5Cfrac%7B%28s_1%29%5E2%7D%7Bn_1%7D%2B%5Cfrac%7B%28s_1%29%5E2%7D%7Bn_2%7D%7D%20%5C%5C%5C%5C)
Put the values in the above formula:
![\to (7.1-8.3) \pm 1.665 \sqrt{\frac{(1.7)^2}{50}+\frac{(1.9)^2}{39}} \\\\](https://tex.z-dn.net/?f=%5Cto%20%287.1-8.3%29%20%5Cpm%201.665%20%5Csqrt%7B%5Cfrac%7B%281.7%29%5E2%7D%7B50%7D%2B%5Cfrac%7B%281.9%29%5E2%7D%7B39%7D%7D%20%5C%5C%5C%5C)
