3) You are implementing a messaging campaign about annual flu vaccines. To evaluate the campaign's effectiveness, you create a survey that asks people to rate their intent to get a flu vaccine on a scale from 0 (not at all likely) to 5 (a certainty). You want to know if the average intention rating changes after the campaign has run in a city. You randomly select people in 35 cities to take this survey before & after the campaign. Use the flu data sheet and R Studio to answer the following questions.
