I need help with the questions in bold only:
Betsy is interested in relating quality of teaching to quality of research by college professors. She has access to a sample of 50 social science professors who were teaching at the same university for a 10-year period. Over this 10-year period, the professors were evaluated on a 5-point scale on quality as instructors and on quality of their courses. Betsy has averaged these ratings to obtain an overall quality rating as an instructor (rating_1) and the overall quality rating of the courses (rating_2) for each professor. In addition, Betsy also has the number of articles that each professor published during this time period (num_pubs) and the number of times these articles were cited by other authors (cites).
1. Conduct a correlational analysis to investigate the relationships among these variables. Identify the following on the output:
a. p value for the correlation between rating_1 and rating_2 - Where is it in the table?
b. Correlation between cites and num_pubs
c. Correlation between cites and rating_1
2. What is the relationship between the number of articles published and the overall quality of the instructor?
