Tax Preparation System Problem (use for first 4 questions) GSB student representatives are organizing a tax preparation system. They expect to receive 100 students, coming to the system within 4 hours at a constant rate. The process consists of a check-in station, where there is a single server that takes 2 minutes to decide whether the student has all the information needed to fill out the forms or not. From previous experience, they know that 80% will be OK, and then, they will go to one of the analysts to complete the tax forms. The other 20% will need to gather the extra info, a process that they do by themselves, and that will take exactly 1 hour. After that hour, they will join the queue for the analysts. There are 5 analysts and each takes 15 minutes to serve a student Standard Loss Function Table z F(z) L(z) zl F(z) L(2) -4.0 0.0000 4.0000 0.0 0.5000 0.3989 -3.9 0.0000 3.9000 0.1 0.5398 0.3509 -3.8 0.0001 3.8000 0.2 0.5793 0.3069 -3.7 0.0001 3.7000 0.3 0.61790.2668 -3.6 0.0002 3.6000 0.4 0.6554 0.2304 -3.5 0.0002 3.5001 0.5 0.69150.1978 -3.4 0.0003 3.4001 0.6 0.7257 0.1687 -3.3 0.0005 3.3001 0.7 0.75800.1429 -3.2 0.0007 3.2002 0.8 0.7881 0.1202 -3.1 0.0010 3.1003 0.9 0.81590.1004 -3.0 0.00133.0004 1.0 0.84130.0833 -2.9 0.0019 2.9005 1.1 0.8643 0.0686 -2.8 0.0026 2.8008 1.2 0.8849 0.0561 -2.7 0.0035 2.7011 1.3 0.9032 0.0455 -2.6 0.0047 2.6015 1.4 0.9192 0.0367 -2.5 0.0062 2.5020 1.5 0.9332 0.0293 -2.4 0.00822.4027 1.6 0.9452 0.0232 -2.3 0.0107 2.3037 1.70.9554 0.0183 -2.2 0.0139 2.2049 1.8 0.9641 0.0143 -2.1 0.0179 2.1065 1.9 0.9713 0.0111 -2.0 0.0228 2.0085 2.0 0.9772 0.0085 -1.90.0287 1.9111 2.1 0.9821 0.0065 -1.8 0.0359 1.8143 2.2 0.9861 0.0049 -1.7 0.0446 1.7183 2.3 0.9893 0.0037 -1.6 0.0548 1.6232 2.4 0.9918 0.0027 -1.5 0.0668 1.5293 2.5 0.9938 0.0020 -1.4 0.0808 1.4367 2.6 0.9953 0.0015 - 1.3 0.0968 1.3455 2.7 0.9965 0.0011 -1.2 0.1151 1.2561 2.8 0.9974 0.0008 -1.1 0.1357 1.1686 2.9 0.9981 0.0005 - 1.0 0.1587 1.0833 3.0 0.9987 0.0004 -0.9 0.1841 1.0004 0.9990 0.0003 -0.8 0.2119 0.9202 3.2 0.9993 0.0002 -0.7 0.2420 0.8429 3.3 0.9995 0.0001 -0.6 0.27430.7687 3.4 0.9997 0.0001 -0.5 0.3085 0.6978 3.5 0.9998 0.0001 -0.4 0.3446 0.6304 3.6 0.9998 0.0000 -0.3 0.3821 0.5668 3.7 0.9999 0.0000 -0.2 0.4207 0.5069 3.8 0.9999 0.0000 -0.1 0.4602 0.4509 3.9 1.0000 0.0000 0.0 0.5000 0.3989 4.0 1.0000 0.0000 3.1 M/M/s Lq Table 8 0.00 #Servers (8) Utilization (p) 1 2 3 4 5 0.02 0.00 0.00 0.00 0.00 0.00 0.04 0.00 0.00 0.00 0.00 0.00 0.06 0.00 0.00 0.00 0.00 0.00 0.08 0.01 0.00 0.00 0.00 0.00 0.10 0.01 0.00 0.00 0.00 0.00 6 7 8 9 10 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 11 12 13 14 15 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.12 0.02 0.00 0.00 0.00 0.00 0.14 0.02 0.01 0.00 0.00 0.00 0.16 0.03 0.01 0.00 0.00 0.00 0.18 0.04 0.01 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.20 0.05 0.02 0.01 0.00 0.00 0.22 0.06 0.02 0.01 0.00 0.00 0.24 0.08 0.03 0.01 0.01 0.00 0.26!
