1. A sample of non-English majors at a selected college was used in a study to see if the student retained more from reading a 19th-century novel or by watching it in DVD form.

(2 points) and what is the type of study design? (3 points). (2) What statistical test would you use? (3 points) (3) Is the test one-sided or two-sided (1point) and how many degrees of freedom are there? (1 point) (4) Write down H0 and H1 (2 points). What is the characteristic of a null hypothesis (H0)? (3 points). (5)Specify the type of errors in a hypothesis test, and what they mean in this study.(
