Step-by-step explanation:
There are 7 books that can go in the first spot.
After a book has been placed in the first spot, there are 6 books left that can go in the second spot.
After that, there are 5 books that can go in the third spot.
So on and so forth.
So the number of ways is:
7×6×5×4×3×2×1 = 7! = 5040
Answer:
The answer is A which is X^3 3 root y
The square root of 34 is 5.83095
A)
<h3>
The sample mean is 52</h3><h3>
The claimed population mean is 44</h3>
---------
The sample mean is the mean found in the survey (of the sample of people). The sample mean is found by adding up the values and dividing by the sample size n. The larger n gets, the closer the sample mean should get to the population mean. This is assuming the sample is random and representative of the population.
The population mean is a claim made by another study/survey/etc. Usually generalized statements such as "Americans spent an average of X dollars (in year Y)" would have X be considered the population mean.

B)
<h3>Sample mean is 3.42</h3><h3>Claimed population mean is 3.56</h3>
--------
Same idea as part A, but we're using different numbers and a different problem context.
==================================
Note: The year numbers and the sample sizes are not used to answer any of the four questions above.
