Some smoke alarms for homes with children now use a recording of the mother’s voice calling the child by name, as opposed to the beeping sound of conventional smoke alarms.
a. Describe how you could design a matched pairs study to investigate whether the new smoke alarms reduce the time needed for a child to wake up and leave the house.
b. Explain why a matched pairs design is likely to be helpful, as compared to a completely randomized design, in this study.
c. Explain why it’s important to randomize the order in which the children receive the treatments.
