Step-by-step explanation:

Sample mean = 21

Standard deviation = 15.255

Confidence level = 0.95

Significance level = 0.05

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.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
