The mean loss for customers at the first State bank (which is not insured) was $150.00 the standard deviation of the losses was -$125.00
So -- to repeat what PsyDag asked you --
What is your question?
comment on the statement "The mean loss for customers at the first State bank (which is not insured) was $150.00 the standard deviation of the losses was -$125.00"
I'm sorry, but there seems to be an error in the information you provided. The standard deviation cannot be negative. The standard deviation is a measure of how spread out the values in a data set are, and it is always a non-negative value.
Please double-check the values and provide accurate information so that I can assist you further.
