[#226] The difference of two means in case of small samples is tested by the formula

(A) $${ ext{t}} = frac{{{{overline { ext{X}} }_1} - {{overline { ext{X}} }_2}}}{{ ext{S}}}sqrt {frac{{{{ ext{n}}_1}{{ ext{n}}_2}}}{{{{ ext{n}}_1} + {{ ext{n}}_2}}}} $$

(B) $${ ext{t}} = frac{{{{overline { ext{X}} }_1} - {{overline { ext{X}} }_2}}}{{ ext{S}}}$$

(C) $${ ext{t}} = sqrt {frac{{{{ ext{n}}_1}{{ ext{n}}_2}}}{{{{ ext{n}}_1} + {{ ext{n}}_2}}}} $$

(D) $${ ext{t}} = frac{{{{overline { ext{X}} }_1} - {{overline { ext{X}} }_2}}}{{ ext{S}}}sqrt {frac{{{{ ext{n}}_1} - {{ ext{n}}_2}}}{{{{ ext{n}}_1}{{ ext{n}}_2}}}} $$

Correct Answer

(B) $${ ext{t}} = frac{{{{overline { ext{X}} }_1} - {{overline { ext{X}} }_2}}}{{ ext{S}}}$$
