Use the graphic to show the sampling distributions of means for the sample from Prison A (n=82) and the sample from Prison B (n=37). Mark the expected value of the mean and the standard units. Shade in the critical zone for alpha = .05.Locate each sample mean after you have marked the standard units. Attach a copy of your drawing or describe the location of the sample mean in each sampling distribution.

We do not have the graphic available, so we cannot help you.
