Answer:
- Monsieur Ernest Defarge
- The knitting of Madame Defarge, wife of Monsieur Ernest Defarge
- The record is kept secret, because knitting is something common that does not arouse suspicion.
Explanation:
The question above shows an excerpt from "A Tale of Two Cities" by Charles Dickens. The excerpt is presented by Monsieur Ernest Defarge. He is talking about a record that is kept secret. This record is the knitting of his wife Madame Defarge, who knits information in code form about the people she and her husband want to kill, for some reason. Nobody is suspicious of this record, because knitting was something very common to be done by women at the time, besides, it was impossible for anyone to be able to unveil the code contained in the knitted piece.
What we are looking for is the confidence interval.
Given:
Sample it is denoted by n = 10
Mean = 80
Standard deviation = 12
Confidence Interval = 99%
Now compute for the margin of error, the formula is Za/2 * σ/√(n)
A 99% level of confidence has a critical value of zα/2 = 2.58.
The standard error is σ/√(n) = 3.162
Multiply 2.58 by 3.162 = 9.8 is the margin of error.
The formula for confidence interval is x̅ ± Za/2 * σ/√(n)
= 80 ± 9.8
= 70.2 < x< 89.8
The correct answer is sources of meaning. This concept serves as a guidance or confrontation of questions that already exist by means of having to define the real meaning behind it or trying to emphasize what's more important or valuable to an individual.
