Studies have linked brain size in infants and toddlers to a number of future ailments, including autism. One study looked at the brain sizes of 30 autistic boys and 12 nonautistic boys (the control group), all of whom had undergone an MRI scan as toddlers.

3. If it is concluded that there is evidence of a difference, obtain a 95% con?dence interval for the mean difference in whole-brain volume in early life between autistic and non-autistic boys. Explain in your own words how the con?dence interval should be interpreted
