An academic is interested in whether international collaboration, measured by the international co-publication rate, is associated with a higher quality of scientific work, measured by the relative impact factor of the publication. The EXCEL file InternationalCollaborations.xlsx (see image attached) contains the international co-publication rate and the relative impact factor of 31 randomly sampled journal articles, and this is Sample A.
Research Question: "Is there a linear relationship between the international co-publication rate and the relative impact factor of the publication?"
Aanalysing the data in EXCEL. Assume the relevant assumptions for linear regression are satisfied and fit a linear regression model to predict the publication's relative impact factor from its international co-publication rate. Use your Excel output and any other information provided to answer the following questions. For each question, either choose a correct option or type the numerical value with a specified number of decimal places into provided answer space.
