he sample standard deviation is s = 5. Use Appendix D to find the values of Student’s t. (a) Construct an interval estimate of μ with 99% confidence. (Round your answers to 3 decimal places.) The 99% confidence interval is from to (b) Construct an interval estimate of μ with 99% confidence, assuming that s = 10. (Round your answers to 3 decimal places.) The 99% confidence interval is from to (c) Construct an interval estimate of μ with 99% confidence, assuming that s = 20. (Round your answers to 3 decimal places.) The 99% confidence interval is from to (d) Describe how the confidence interval changes as s increases. The interval stays the same as s increases. The interval gets wider as s increases. The interval gets narrower as s increases.

When you substitute a value for x or y, you are x or y with a value.
Hitman42 [59]

Step-by-step explanation:

See whenever we have two variables like x and y.

And also we have given two equations in terms of x and y.

Example: ax + by = p  and cx + dy = q

In order to get the solution, we need to find the value of x and y using the given two equations.

So here what we can do is:

Consider any one equation and get x or y from that equation.

i.e consider ax + by = p  or x = \frac{1}{a}*(p-by)

Now plug value of x (or y) from the equation you have considered into the another equation.

i.e c(\frac{1}{a}*(p-by))+dy = q

Now solve this equation to get y (or x).

and after that we can find the other variable.
