A 2012 survey of WSU undergraduate students found that 43% used Pinterest.  In the Fall 2018 semester, a similar survey was given to a random sample of 78 WSU undergraduate students.  Of the 78 students who responded, 54 said they use Pinterest.

Research Question – Is there evidence that WSU undergraduate students are more likely to use Pinterest in 2018 than in 2012?

1. Identify the population of interest. 

2. Identify the parameter of interest, making sure to use the appropriate statistical notation. 

3. Describe in context how the Binomial Distribution can be used to model this scenario. 

4. Carry out the formal hypothesis test that would be used to test the research question of interest.  Make sure to include the appropriate hypotheses, indicate the value of the p-value, and make your conclusion in context of the research question.
