A study's zz statistic equals its estimated effect measured in standard errors. The true effect is exactly 1 standard error, so zz is normal with mean 1 and standard deviation 1. Only results with z>1.96z > 1.96 get published. What is the average zz (the average published estimated effect, in standard errors) among the published results? Round to the nearest hundredth.
