The researchers want an estimate (or inferred value) for the mean spending and its likely range for the entire population. a) (5 points) Estimate the range in which we expect to find the population mean for spending by constructing a confidence interval. This must be done BY HAND. Round to 4 decimal places and show all your work. Assume the population standard deviation is 16. Use a 95% confidence level. Provide the appropriate values on the lines below.

Answer for the question :

Is explained in the attachment.

Step-by-step explanation:

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
