Suppose that two variables, x and y, are negatively associated. does this mean that above-average values of x will always be associated with below-average values of y? explain.
choose the correct answer below.
a. no, because there will always be at least one point that does not fit the trend.
b. no, because association does not mean that every point fits the trend. the negative association only means that above-average values of x are generally associated with below-average values of y.
c. no, because when two variables, x and y, are negatively associated, above-average values of x are associated with above-average values of y.
d. yes, because if one or more above-average values of x are associated with above-average values of y, the variables cannot be negatively associated.

B. No, because association does not mean that every point fits the trend. The negative association only means that above-average values of X are generally associated with below-average values of Y.

Step-by-step explanation:

If two variables, X and Y, are negatively associated, then the curve that fits its correlation has a negative slope (assuming that the relation was linear). Therefore, when values of X increase, values of Y decrease and vice versa. But this doesn't guarantee that all above-average values of X will always be associated with below-average values of Y because not every point fits the trend.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
