It is public opinion and knowledge that no end of deception is practiced and a thousand acts of robbery and violence are committed in the course of bartering and carrying off Negroes from their country and bringing them to the Indies and to Spain. . . . Since the Portuguese and Spaniards pay so much for a Negro, they go out to hunt one another without the pretext of a war, as if they were deer; even the very Ethiopians, who are different, being induced to do so by the profit derived. . . . They embark four and five hundred of them in a boat which, sometimes, is not a cargo boat. The very stench is enough to kill most of them, and, indeed, very many die. The wonder is that twenty percent of them are not lost. -Source: Fray Tomas de Mercado, Spanish Dominican Friar, 1587 The excerpt is best understood as a response to which of the following historical developments?

explanation:

they were citizens but they could not vote and they did could not get involved into a political situation during that time.

a hypothesis is an expected answer to a question, usually based on some theory or prior research. hypothesis testing is a method of determining the viability of a hypothesis. let’s use the us presidential election as an example. there are many hypotheses (questions) about how people feel or whom they will vote for. the only way to know the 100% “truth” about the answers to these questions is to ask every single possible voter – something that is impossible, expensive, time consuming etc. instead, we take samples and use statistics to make “best guesses” about the answer to a particular hypothesis. we never know for sure if our conclusion is right at the time we accept/reject it, but these techniques, when used appropriately can get us close to the truth most of the time (which is a lot better than guessing, flipping coins or throwing darts to get answers).

the tricky part about hypothesis testing is that we have to think somewhat backwards about it – we have to test what is known as the “null hypothesis”. as an example, the hypothesis might be “obama is more popular than romney” while the null hypothesis is “there is no difference in popularity between obama and romney”. we focus on the null hypothesis because it tells us exactly what the expected value of our tests should be (obama popularity = romney popularity) and we can collect data and see if it comes out that way (see next section on “significance”). if it does, then we “accept the null hypothesis” and reject our original hypothesis. if the null hypothesis is disproven, we look at the data to see if our original hypothesis holds (obama> romney).
