If the Null Hypothesis $H _ { 0 } : \mu = 17.0$

If the null hypothesis $H _ { 0 } : \mu = 17.0$ is rejected at $\alpha = 0.10$ when a mean of $20.0$ is obtained from a random sample, one could also say that

A) the 90% confidence interval for the population mean contains the value 20.0.
B) the 10% confidence interval for the population mean contains the value 20.0.
C) the 10% confidence interval for the population mean does not contain the value 17.0.
D) the 90% confidence interval for the population mean does not contain the value 17.0.
