a. Is the following statement true or false "The single-phase, single-channel model with Poisson arrivals and undefined service times will always have larger (i.e., greater) operating characteristic values (i.e., W , W q , L , L q ,) than the same model with exponentially distributed service times." Explain your answer.
b. Is the following statement true or false "The single-phase, single-channel model with Poisson arrivals and constant service times will always have smaller (i.e., lower) operating characteristic values (i.e., W , W q , L , L q ) than the same model with exponentially distributed service times." Explain your answer.
