Answer:
C. populations are non normal and the sample sizes are large.
Step-by-step explanation:
To test hypotheses about the difference between two populations means we deal with the following three cases.
1) both the populations are normal with known standard deviations.
2)both the populations are normal with unknown standard deviations.
3) both the populations are non normal in which case both the sample sizes are necessarily large.
So option C is the correct answer.

8/9 - 3/9 = 5/9
1/2 of a chance he will often grab a yogurt (as there is a total of ten items (5/10). 2/10 (1/5) of a chance he will grab a green apple. and 3/10 of a chance he will grab a red apple. he will have around a 1/5 chance to not grab a yogurt on 3 consecutive days.

Each piece is 20 inches long.
Step-by-step explanation:
The length pieces of the ribbon can be obtained by dividing the total length of ribbon by total number of pieces
Given
String length = 168 inches
Number of pieces = 6
So the length of each piece will be:
Cutting 8 inches from each piece means that the length will be reduced 8 inches
Hence,
Each piece is 20 inches long.
