为什么不选C啊

问题如下：

When an investigator wants to test whether a particular parameter is larger than a specific value, the null and alternative hypothesis are best defined as:

选项：

A.

H₀: θ = θ₀versus Ha: θ ≠ θ₀

B.

H₀: θ ≤ θ₀versus Ha: θ > θ₀

C.

H₀: θ ≥ θ₀versus Ha: θ < θ₀

解释：

A positive “hoped for” condition means that we will only reject the null (and accept the alternative) if the evidence indicates that the population parameter is greater than θ0. Thus, H0: θ ≤ θ0 versus Ha: θ > θ0 is the correct statement of the null and alternative hypotheses.
