Develop a simple simulation using Excel for the Play Dough process. For simplicity, consider the rolling and cutting processes only. Assume that the rolling follows an exponential distribution with a mean of 1 minute (1/lambda), and the cutting follows a uniform distribution of 0.25 to 0.5 minutes. You can use the following column names to develop your simulation:

Unit number Rolling time Cutting time Finish time Total time Waiting time Simulate the process for a 100 units and calculate the average total time and average waiting time.
