Answer:
The correct option is - D
The probability that the test rejects H₀ when m = 1 is true.
Explanation:
Given,
The significance level of a test
H₀ : m = 1 versus Hₐ : m > 1
Given options were
A) the probability that H₀ is true.
B) the probability that the test fails to reject H₀ when m = 3 is true.
C) the probability that the test rejects H₀ when m = 3 is true.
D) the probability that the test rejects H₀ when m = 1 is true.
Therefore, D means that The alternative hypothesis (Hₐ) will reject the Null hypothesis (H₀) when m = 1.
