Hi I need help with this problem I am not sure how I would solve it. “In a distribution, the number seven has a Z score of -2 and the number 19 has a Z score of 1. What is the mean of the distribution?” I am not giving the standard deviation or any other information so I’m not sure how I would solve this. Thank you!

You are ALMOST given the Standard Deviation.
Z-Score ------(-2) -------(-1)--------(0)--------(1)----------(2)
Std Dev ------(-2) -------(-1)--------(0)--------(1)----------(2)
Prob Stmt ------(7) -------(??)--------(??)--------(19)----------(??)
What say you? Can you spot the Standard Deviation in there?
