Answer:
n=2
Step-by-step explanation:
3n-7=3-2n
5n=10 (add 2n on both sides and also add 7 on both sides of the equal sign)
n=2

The solutions to the questions are given below
a)
sample(n) word length sample mean
1 5,4,4,2 3.75
2 3,2,3,6 3.5
3 5,6,3,3 4.25
b)R =0.75
c)
- The mean of the sample means will tend to be a better estimate than a single sample mean.
- The closer the range of the sample means is to 0, the more confident they can be in their estimate.
<h3>What is the students are going to use the sample means to estimate the mean word length in the book.?</h3>
The table below shows sample means in the table.
sample(n) word length sample mean
1 5,4,4,2 3.75
2 3,2,3,6 3.5
3 5,6,3,3 4.25
b)
Generally, the equation for is mathematically given as
variation in the sample means
R =maximum -minimum
R=4.25-3.5
R =0.75
c)
In conclusion, In most cases, the mean of many samples will provide a more accurate estimate than the mean of a single sample.
They may have a higher level of confidence in their estimate if the range of the sample means is closer to 0 than it is now.

So first you would have to do is read the problem carefully and understand what it's asking you and what I mean is look for some clues that would help you to solve the problem. For instance, the word fewer is a good word to help us because the word fewer means less or taking away and so what that tells us is, what we have to do is subtract 1089 points from 14370 points they want to know how many points did Amy scored and so in order to do that we need to subtract and so our final answer would be 13281 as our final answer and so thank you for this question and keep in mind that you always have to read the question carefully in order to understand. So Amy scored 13281 in the game. Have a blessed day.
