-In testing the hypotheses:
H₀: $\mu _ { 1 } - \mu _ { 2 } = 0$ H1: $\mu _ { 1 } - \mu _ { 2 } \neq 0$ t
wo random samples from two normal populations produced the following statistics: n₁ = 50, $\overline { \mathrm { X } } _ { 1 }$ = 35,s₁ = 28,n₂ = 50, $\overline { \mathrm { X } } _ { 2 }$ = 30,s₂ = 10.What conclusion can we draw at the 5% significance level?
