A lоgistics mаnаger is аnalyzing the delivery times оf a specific cоmponent from a supplier. The population standard deviation of delivery times is known to be 2 days. From a random sample of 144 deliveries, the manager calculates a sample mean delivery time of 10 days. Due to a recent change in the supplier's transportation network, the manager suspects that the true population mean delivery time may have shifted. They want to calculate a 95% confidence interval to assess this. However, during a system update, the sample size was inadvertently recorded as 169 instead of 144. Using the incorrect sample size of 169, what is the approximate 95% confidence interval for the population mean delivery time of the component?
