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:
This is your answer ☺️☺️☺️
Answer:
-2
Step-by-step explanation:
all you gotta do is look to see where the line intersects the y axis which is -2 here
Answer:1/4x+y=-3
Step-by-step explanation:
You have to move 1/4x to the left side by adding the inverse of 1/4x, -1/4x to each side. Then you have 1/4x+y+3=3. After this you have to use the subtraction property of equality. Then your answer is 1/4x+y=-3
