A research study was conducted to determine if children with attention deficit/hyperactivity disorder, ADHD, have smaller brains than children without the condition. She computed a z score of -1.73. Using a left tailed test of hypothesis, find the p-value, and at a 5% confidence level, determine if the data provids evidence that children with ADHD have smaller brains than the children without the condition.
