2. Consider a simple prooseving psiem with an intrearrival time (NT) distribution and a. proess time (IT) distributios gives in Takis 1 and Tatie 2 reopectivily. Table 2 in 1) Calculate the mean and standand deviation o\& UT. 2) Cakulate the mean and standard deviaban of PT: 3) Suppose we are intereate in the waiting time and be time in vystem per purt. A simulation was performod untif the sylem proconed 20 parts as shown in Table 3. top to botioen. Yoo donit have to re-wnie the whole bble) b. Coepare the means and stder's a WT and PT obtalend trum the samslation to thote obained in parts 1 and 2 Irielly explain what you think about the simulation
