Given that the experimental group (n=30) and the control group(n=30) had the largest difference in disaster readiness (see table3), calculate the standard error of mean difference for disasterreadiness. Let experimental represent sample 1 and controlrepresent sample 2. Use posttest sample standard deviations in yourcalculations and three decimal places.
