I assumed that 3 households are sampled.
Now, is the number in each of these households equal to 1, 3 and 8 people?
Next, the question says, samples of n=2 are randomly selected (with replacement) from these 3.
So are sample space is
11
13
31
33
18
81
38
88
83
88
This is done 9 times.
Is that how you understand the problem?
When they select the household with only 1 person, the variance is 0
When they select the household with 8 people, they variance will be from a discrete uniform distribution
Similarly for household with 3 individuals.
The answer to your question is 260
Answer:
Step-by-step explanation:
Your dumb
6b - 8 = 8b - 11
11 - 8 = 8b - 6b
3 = 2b
b = 3/2 = 1.5
