The ages (years) of three government officials when they died in office were 56,45 , and 60 . Complete parts (a) through (d).
a. Assuming that 2 of the ages are randomly selected with replacement, list the different possible samples.
A. $(56,45),(56,60),(45,60)$
B. $(56,56),(56,45),(56,60),(45,45),(45,60),(60,60)$
C. $(56,56),(56,45),(56,60),(45,56),(45,45),(45,60),(60,56),(60,45),(60,60)$
D. $(56,45),(56,60),(45,56),(45,60),(60,56),(60,45)$
b. Find the range of each of the samples, then summarize the sampling distribution of the ranges in the format of a table representing the probability distribution.

Answer
Final Answer: The different possible samples of ages when 2 of the ages are randomly selected with replacement are \(\boxed{[(56, 56), (56, 45), (56, 60), (45, 56), (45, 45), (45, 60), (60, 56), (60, 45), (60, 60)]}\). This corresponds to option C in the question.
Step 1 ：The problem is asking for the different possible samples of ages when 2 of the ages are randomly selected with replacement. This means that after selecting an age, it is put back into the pool and can be selected again.
Step 2 ：The ages of the officials are 56, 45, and 60.
Step 3 ：We can list all the possible samples of ages when 2 of the ages are randomly selected with replacement as follows: (56, 56), (56, 45), (56, 60), (45, 56), (45, 45), (45, 60), (60, 56), (60, 45), (60, 60).
Step 4 ：Final Answer: The different possible samples of ages when 2 of the ages are randomly selected with replacement are \(\boxed{[(56, 56), (56, 45), (56, 60), (45, 56), (45, 45), (45, 60), (60, 56), (60, 45), (60, 60)]}\). This corresponds to option C in the question.
