1. Use the Random Babies applet for this problem. On your computer, type in http://www.rossmanchance.com/applets/randomBabies/RandomBabies.html. This applet is simulating the following scenario. When their name tags are lost, four babies are mixed up at a hospital. Then each baby has to be assigned randomly to a family. The simulator simulates a random assignment of babies to families, and it records the number of correct matches (outcome) of baby with family. Make sure that the "Number of babies:" is set to 4.
   1. (a) Set the "Number of trials:" to 1 and make sure the "Animate" box is checked. Watch at least 5 trials being simulated by click the "Randomize" button. Then, un-check the "Animate" box and enter the remaining number of trials needed to have 1000 total trials; hit the "Randomize" button. Sketch the graph you see.
   2. (b) What percentage of trials returned all four babies to the correct families?
   3. (c) Using the "Average" option, record the mean you are given from the plot on the bottom- right (giving units). Interpret this mean.

(d) Looking at the Histogram, describe what you see in the slot representing exactly 3 matches, and explain why this makes sense.
