An airline wants to find out how long it takes for a travel agent to complete an airline ticket order from a computer terminal. Assume that the mean transaction time is 150 seconds. also assume that the population of transaction times has normal frequency curve. Find the probability that the 150 and 175 seconds to complete if standard deviation is 30 seconds.© BrainMass Inc. brainmass.com March 4, 2021, 5:56 pm ad1c9bdddf
