In an experiment, one group of research participants is given 10 pages of material to proofread for errors. Another group proofreads the same material on a computer screen. The dependent variable is the number of errors detected in a 5-minute period. A .05 signifi cance (alpha) level is used to evaluate the results.

a. What statistical test would you use?

b. What is the null hypothesis? The research hypothesis?

c. What is the Type I error? The Type II error?

d. What is the probability of making a Type I error?
