Reading condition and confidence in voting decisions. What is the most appropriate statistical test?

A researcher examined whether exposure to different campaign messages influences trust in local government. Participants were randomly assigned to read either a message emphasizing government transparency reforms or a message emphasizing government inefficiency. After reading the message, participants completed a 10-point scale measuring trust in local government.Results:Transparency message mean = 5.1Inefficiency message mean = 6.7F = 7.44p = .011

Compare and contrast the “interesting pairs” of the four bivariate data analysis models we are working with. 

A student proposes the following Lewis structure for the isocyanate ion, NCO-. Assign a formal charge to each atom in the student’s Lewis structure. atom formal charge C N O
