Explanation & Answer
Thank you for the opportunity to help you with your question!
To solve this problem, you need to solve for one variable in one equation, then substitute that variable into the other equation:
1. Solve for c in the first equation:
c-5d=-16
c=5d-16
2. Plug c into the second equation, then solve for d:
3c+2d=-14
3(5d-16)+2d=-14
15d-48+2d=-14
17d=34
d=2
3. Now plug d into either equation to solve for c:
c-5d=-16
c-5*2=-16
c-10=-16
c=-6

Confidence Interval Problem Discussion
Write a confidence interval problem:
Option 1:
Think about a population mean that you may be interested in and propose a confidence interval problem for this parameter. Your data values should be approximately normal.
For example, you may want to estimate the population mean number of times that adults go out for dinner each week. Your data could be that you spoke with seven people you know and found that they went out 2, 0, 1, 5, 0, 2, and 3 times last week. You then would choose to calculate a 95% (or another level) confidence interval for the population mean.
Assume a random sample was chosen, which is required to determine a confidence interval.
