Type your answer.1 point )9 Alex had a bag of 500 game tiles. each labeled with a number: 1,2, 3. 4, or 5.Alex decided to create a sampling distribution for this bag of game tiles. To do so, Alex pulled 10 random tiles out of the bag and took the average of the numbers. Alex then did this 19 more times, so there were twentyr sample averages. each including the average of the numbers written on a random sample of 10 tiles. Alex then graphed these averages and called it a sampling distribution. What Alex created was NOT actually a sampling distribution though. Why not? A sampling distribution would have to include the individual values from each tile, not the average A sampling distribution would have to include samples of everv possible size that oould be pulled from the bag of tiles. A sampling distribution would have to include everyr possible sample of 10 that could be pulled from the bag of tiles. 2 points This Venn diagram shows the sample space and eventsA and prr a double roll of a foursided die.
