One sample t-test to compare deviation from baseline?

General
1

Hi everyone! I am not very good with stats an I am trying to identify the significance of any variation from a baseline value for the control groups in my meta-analysis. I have the following data for each study included in my meta-analysis:

-sample size of control group
-mean of each control group
-standard deviation of each control group

I want to compare the overall deviation from a baseline value of 220.

What would be the best test to conduct on this data and what would be the best way to visualize it?

Thank you for your help!

Perhaps something like

z = abs(mean - 220)/(stddev/sqrt(n-1))

And then compare z to 1.96 (for the most common significance level) or whatever.
