Essay

You are studying two normally distributed populations with equal variances.A random sample is taken from each population.The relevant sample statistics are $\bar { x } _ { 1 }$
= 34.36, $\bar { x } _ { 1 }$
= 26.45,s₁ = 9,s₂ = 6,n₁ = 10,n₂ = 16.Compute a 95% confidence interval for $\mu _ { 1 } - \mu _ { 2 }$
.
