The question was a bit confusing, and I have been searching for similar question. I found a picture similar to description about the dot plot as below:
1: 4 dots
2: 8 dots
3: 4 dots
4: 2 dots
5: 1 dot
Answer:
It never took more than 4 rolls to get an even number
Step-by-step explanation:
Total dots by even number: 8 + 2
Pr(even) = 10/19 = 1/1.9
In other word, for every 1.9 rolls (or 2 rolls), 1 will be even.
The data is skewed to the right since most of the rolls occupied by number 1,2 and 3.
And there is no prove that the event is being clustered, hence less likely to be cluster sampling
It doesn't take 3 rolls to get even number. 2 rolls needed to get even number.
The most correct answer should be 'it never take more than 4 rolls to get even number' since it only took 2 rolls to get an even number.
