Dr. Collyer and Dr. Castañeda decide to invite local health officials to the college to hold a panel presentation on the local impact of COVID. The day before the presentation, students respond to the COVID risk perception survey. The next day, they attend the panel presentation and immediately after take the COVID risk perception survey again to see if their perception of risk has changed. Was there a change in the level of risk perception due to the panel's presentation on COVID (α = .05)?
