Beskou die volgende hipotese toets: / Consider the following hypothesis test:

H₀: µ₁ - µ₂ = 0

H₁: µ₁ - µ₂ > 0

Die volgende resultate is van onafhanklike steekproewe uit twee populasies verkry: / The following results were obtained from independent samples from two populations:

Steekproef 1 / Sample 1:                 n₁ = 35            x̄₁ = 14.6                     s₁ = 6.4

Steekproef 2 / Sample 2:                 n₂ = 40            x̄₂ = 10.8                     s₂ = 8.3

Die standaardfout van   indien die populasievariansies as gelyk aanvaar kan word, is / The standard error of   if the population variances can be assumed to be equal, is
