Question

Let X1, X2 ,…, X25 be a random sample from a 𝑁(μ, 1) distribution, where μ ∈ $\R$ is unknown. Consider testing of the hypothesis H0 : μ = 5.2 against H1 : μ = 5.6. The null hypothesis is rejected if and only if $\frac{1}{25}\sum^{25}_{i=1}X_i > k$ , for some constant k. If the size of the test is 0.05, then the probability of type-II error equals __________ (round off to 2 decimal places)

Answer 1

The correct answer is 0.34 - 0.38.(approx)
