Default Re: Finding a probability from a Mean and a Standard Deviation
I wasn't given the distribution.

The question is similar to this one, not exactly the same.

A recent study found the average weight of 5 year olds is 62 pounds with a standard deviation of 8.1 pounds. If a 5 year old is selected at random, what is the probability that their weight will be less than 70 pounds.

Thanks.
