| dipu617 | Could anyone please clarify? Thank you. |
| robertucla | It's in the first sentence in def dipu617 |
| dbedford | The null hypothesis Ho is represented by the tail(s) of the population's normal distribution and we want to reject the idea that the unknown parameter typically the mean is in the tail(s) and not toward the center |
| jgoff508 | Dipu617, Boston area? Someone please correct me if I'm wrong but, think of if this way. The null is making a claim about an entire group. The alternative is suggesting that the null isn't accurate, and make it's own claim. |
| thevinu | Null Hypothesis speaks for an entire population parameter while alternative tries to reject the hypothesis using a sample statistic. |
I am happy to say that I passed! Your study notes certainly helped prepare me for what was the most difficult exam I had ever taken.
