Assuming that you want to generalize to all cancer patients, all cancer patients would be the population, the 675 patients would be the sample, and the 76% and 63% are statistics.

**Statistics**

Wouldn't the probability of rejecting the null hypothesis be easier(more likely), if you have a larger alpha level? In other words, if you are using P=.05 it is easier to reject the null hypothesis than if you were using P=.01.

**Stat**

Do you have a typo? It would take an extremely deviant score (>100) to drop the mean from 100 to 9 by omitting it.
