Duthler {2006) suggests that politeness will vary depending on the type of channel used {voicemail versus email)I and also by the degree of imposition of the message's request. He developed the following hypotheses. H1; Imposing requests will be rated higher on measures of politeness than unimposing requests. H2: Electronic mail requests will be rated higher on measures of politeness than voicemail requests. a) Identify the independent variable for H1. bi Identify the independent variable for H2. c) Identify the dependent variable (it is the same) for both hypotheses. d] Name the statistical test you would use to test these two hypotheses together.
