A bank manager wants to learn more about the time a customer has to wait to be served. He measures waiting time for a sample of 7 randomly selected customers and finds the following values (in seconds): 43, 39, 40, 75, 34, 86, 125. Find a point estimate of the population standard deviation of the wait time.

If required, round your answer to two decimal places.
