Is it possible to test a hypothesis to show that there is no significant difference between two averages without a standard deviation for both sample sets?
I have a problem involving two sets of data, salaries for location 1 and for location 2. Problem is I don't have any info on location 1 except the average, no knowledge of the std dev or sample size. I do however have this information for location 2.
Any ideas on how to show no significant difference between the two averages with such limited information?
