Following are the solution parts for the given question:
For question A:
In the given question, we calculate of the confidence interval for the mean weight of shipped homemade candies that can be calculated as follows:
Using the t table we calculate When of the confidence interval:
So confidence interval for the mean weight of shipped homemade candies is between .
For question B:
Here we need to calculate confidence interval for the true proportion of all college students who own a car which can be calculated as
Using the Z-table we found
therefore the confidence interval for the genuine proportion of college students who possess a car is
So the confidence interval for the genuine proportion of college students who possess a car is between
For question C:
- In question A, We are certain that the weight of supplied homemade candies is between 392.47 grams and 427.53 grams.
-
In question B, We are positive that the true percentage of college students who possess a car is between 0.28 and 0.34.

Answer:
502.4 mm^2
Step-by-step explanation:
First find the area of the larger circle, and then that of the smaller one.
Then subtract the latter (2nd) area from the first.
larger circle area smaller circle area
------------------------- ---------------------------
3.14(14 mm)^2 3.14(6 mm)^ 2
This comes out to 3.14[14^2 - 6^2] mm^ 2 = 3.14[196 - 36] mm^2, or
3.14(160 mm^2) = 502.4 mm^2
The area of the metal washer is 502.4 mm^2.
