3. (10 points) Your 5- grade class is having a "guess how many candies are in the jar" contest. Initially there are only red candies in the jar. Then you show the children that you put 20 green candies in the jar (same type of candy). Tyler is blindfolded and allowed to pick 20 candies out of the jar. Of the candies Tyler picked, 4 are green; the other 16 are red. Based on this experiment, what is the best estimate we can give for the total number of candies in the jar? Explain how to solve this problem using the idea of "batches". 4. The dot plot below represents the number of red candies found in some packets. 0000 000000 0 1 2 3 4 5 6 7 8 9 10 a. [2 ptsl Calculate the mean number of red candies in a packet. b. [5 pts] Use one of the "meanings of the mean" to explain why your answer above is reasonable.
