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.
Answer:
3.6
Step-by-step explanation:
if 0.45 is 1 pound then you could do 8 x 0.45 because the baby is 8 pounds
Answer:
Step-by-step explanation:
Total number of people that attended the high school's football games last year was 23,125.
Total number of people that attended the high school's football games this year is 22,758. Therefore is a decrease in the number of people that attended last year when compared to this year. The decrease in the number of attendees is 23,125 - 22,758 = 367
The percent decrease in number of attendees will be
367/23125 × 100 = 1.587%
12.) To get to 6 to 24, you multiply it by 4. So, in order to get 5 to a certain number, you must also multiply it by 4.
5 times 4 is 20. So, 20 would be A.
14.) To get 3 to 15, you multiply it by 5. So, in order to get 1 to a certain number, you must also multiply it by 5.
1 times 5 is 5. So, 5 would be A.
Hope I helped!
