In a particular hospital, 6 newborn babies were delivered yesterday. Here are their weights (in ounces):
112, 96, 109, 126, 99, 106
Assuming that these weights constitute an entire population, find the standard deviation of the population. Round your answer to at least two decimal places.

Mean=648/6= 108
I can find the mean but can’t remember what I do next.

I'm sure your textbook has instructions on how to find the standard deviation. AND, there should be literally hundreds of websites with that information as well.

Here's ONE:
