Answers: Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Explain.
Mean for both bakeries because the data is symmetric Mean for Bakery B because the data is symmetric; median for Bakery A because the data is not symmetric Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric Median for both bakeries because the data is not symmetric

Answer:
(5,3)
Step-by-step explanation:
If you graph the equation and plot all the points given as options, you can see that (5,3) lies on the line, while all others don't. This means that option D (5,3) would get generated by the equation.
Another way to do this is to substitute 'x' and 'y' for the points given. If they satisfy the equation, then it would be correct.
<h3>Option A (5,7):</h3>Option A is incorrect.
<h3>Option B (7,14):</h3>Option B is incorrect.
<h3>Option C (7,9):</h3>Option C is incorrect.
<h3>Option D (5,3):</h3>Option D is correct.
Option D should the the correct answer.
Answer:
The sample size must be greater than or equal to 756
Step-by-step explanation:
The formula to calculate the error of the proportion is the following
where p is the proportion, n the sample size, E is the error and z is the z-score for a confidence level of 95%
For a confidence level of 95%
We know that for this case
We require that the error be 0.03 as maximum
Therefore we solve for the variable n
