Radioactive Dating Game [3.27) file nlp iinuulElhm i i Report the value for the half-life you found by rolling 100 dice. Also report the average half-life and the standard deviation calculated from the whole class multiple trials. If you need help doing this calculation, go back to the very first popcorn lab module and review the definitions and how to use Excel for statistics. By what factor are the statistics for the whole class sample larger than your individual measurement? In what way is the result better for the whole class sample? How many sigmas away is your individual measurement from the class average? Comment on whether the whole class sample is more precise or more accurate or both. How would the half-life of this experiment have changed if you had used a 20-sided dice? Is a 20-sided dice a model for a longer or a shorter decay time? Attach your answers to Part II to your lab report or as a second pdf file
