B. probability is high that in the population, MU = 50
C. the sample data are not inconsistent with the hypothesis that in the population, MU = 50

surob Why not all are correct?
ConorOG you can't say the population , MU = 50 without sampling the entire population.
bdaguy And just because MU=50 is a possible answer, it doesn't mean that it's a likely answer. Therefore, B is rejected.
apiccion Being unable to reject something does NOT mean that:
A) It is true.
B) There is a high or 'higher' probability that it's true.

For example, consider that I want to prove that there are no invisible pink unicorns. Then my null hypothesis is: "There are invisible pink unicorns". Obviously, any experiment I do will fail to disprove the null hypothesis. But clearly the notion that invisible pink unicorns exists is absurd.

This is similar to proving the existence of god. You can never disprove the existence of god, but being unable to prove the existence of something does not imply that it must exists.
bundy However apiccion there is proof of God..so bad analogy
JakeZ lets not get into there guys :)
