The mean waiting time at a drive-through of a fast-food restaurant from the time the order is received is 84 seconds. A manager devises a new drive-through that he believes will decrease wait time. He initiates the new system at his restaurant and measures the wait time for 100 randomly selected orders. The sample mean is 81 seconds with a standard deviation of 3.6 seconds. Assume that wait times are normally distributed. The manager conducts a hypothesis test to determine if the new system decreases wait time. (alpha=0.05)
What is the standard score?
