A small stationary store has about 2500 pens in the store and wants to estimate the mean retail value of pens that it has in its inventory. A random sample of 100 pens is selected and the computed mean of the sample is $2.64 and a standard deviation of $0.44. Assuming a normal distribution, construct a 95% confidence interval of the mean value of all the pens in the store.
