A pediatrician's office wanted to know whether parents were happier with their practice if they provide one waiting room for all patients, separate waiting rooms for sick and well children, or had no waiting room and families were shown directly to exam rooms. Families were randomly assigned to one of those three groups. Their scores on a satisfaction survey.

a) Can the office determine if there was a significant difference between the waiting room conditions (shared vs. separate vs. none) at α = 0.05? Show all necessary components of a full hypothesis test, including a source table.
b) Perform a Tukey's HSD post-hoc test for the difference between the shared and separate conditions. Is this a significant difference?
