Question

Roll two dice 10 times. Record the sum of the dice for each roll. Find the mean, standard deviation, and construct a histogram from the data. Roll two dice 50 times. Record the sum of the dice for each roll. Find the mean, standard deviation, and construct a histogram from the data. Roll two dice 100 times. Record the sum of the dice for each roll. Find the mean, standard deviation, and construct a histogram from the data. Summarize your findings by discussing the statistical implication of your findings.

Explanation / Answer

Instead of rolling the dice I will create a simulation which gives random results of what could happen when we roll two dices. I will use the function rand in EXCEL.

For part 1 , 2 and 3 please look up in the excel file.

Part 4.

As the number of simulations increase, the histogram becomes more and more symmetric.
