If the Value of the Sample Mean $\bar { x }$

If the value of the sample mean $\bar { x }$ is close enough to the hypothesized value If the value of the sample mean $\mu$ ₀ of the population mean If the value of the sample mean , then:

A) the value of If the value of the sample mean If the value of the sample mean $\mu$ ₀ is definitely correct.
B) the value of $\mu$ ₀ is definitely wrong.
C) we reject the null hypothesis.
D) we cannot reject the null hypothesis.
