A researcher is interested in whether using personal pronouns in emergency warnings would be more effective during an emergency. 56 participants were presented with a written emergency warning for an upcoming category 4 hurricane. The first group (n=27) received the written warning with the personal pronoun of "you" (e.g., "You should seek a shelter immediately."), and the second group (n=29) received the written warning without the personal pronoun (e.g., "Everyone should seek a shelter immediately."). After they were presented with the emergency warning, they were presented with a survey including questions on the possible next steps they could take. Participants' responses to the questions were recorded on a 4-point scale. Higher scores indicate higher agreement to taking necessary steps (higher effectiveness of the warnings). You can find the dataset for this question on Blackboard. Using the 4-step hypothesis testing, what should this researcher conclude
