Q: The Anderson=s Super Dollar had two grocery stores in Erie, Pennsylvania. The mean time customers wait in the checkout line at the Byrne Road store is 3.7 minute with a standard deviation of .8 minutes, for a sample of 40 customers. The mean waiting time for the I-90 store is 3.5 minutes with a standard deviation of .7 minutes for a sample of 45 customers. At the .05 significance level can we conclude there is a difference in the waiting time for the two stores?
