Question
Determine which statistical method(s) is/are appropriate to answer the question(s). You do not need to perform any actual analyses. Just state the method(s) that will best answer the questions. Give a one sentence explanation for your choice in each case. (You may assume all necessary assumptions are met, such as normality, common variance, etc., when they apply.) Your choices are:
Hypothesis tests and/ or confidence intervals
for a single population proportion to compare two population means using independent samples
for a single population mean to compare two population proportions
for a single population variance to compare two population means using paired data
to determine independence/dependence of rows and columns in a table
Checking for the existence of a linear relationship with a scatter plot and correlation
When research journal articles are submitted for publication, they are typically reviewed by other experts before they are accepted or rejected. A large sample of 13,000 article submissions recorded. Suppose that when the articles are reviewed “blind” (that is, authors and their institutions not identified), 27% were accepted. But when the review was not “blind,” 29% were accepted. How could journal editors determine whether or not “blind” review affects the acceptance rate?
