What does the sample statistic of 5/11 mean?

Question

What does the sample statistic of 5/11 result in a z score that is 1 standard deviation below 0 mean? 

Answer 1

Essentially the idea here is that the Z score of -1 tells you that your sample result of 5/11 is less than the population mean and is situated at a distance of one standard deviation away from the mean. Knowing that value allows you to see how unusual or typical your sample result is compared to the expected outcome.
