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

H₀: µ₁ - µ₂ = 0

H₁: µ₁ - µ₂ > 0

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

Steekproef 1 / Sample 1:                 n₁ = 35             x̄₁ = 13.6                    s₁ = 5.2

Steekproef 2 / Sample 2:                 n₂ = 40             x̄₂ = 10.1                    s₂ = 8.5

Bereken die standaardfout indien die populasie variansies as gelyk aanvaar kan word. / Calculate the standard error if the population variances can be assumed to be equal.
