Read the statements and complete the acknowledgment certifying your agreement.  I have read the proctoring resources. I have followed the directions for installing what is needed for proctoring (e.g., Lockdown Browser, Honorlock, etc). I know where/who/how to ask for help if I have technical questions or issues. I can review the “Proctoring” section or the “Technology Support” page as needed. I have Chrome and I have downloaded the Honorlock Chrome Extension.

Problem 3. A tech startup tests 4 keyboard layouts (A, B, C, D) to see which yields faster typing speed (words per minute) for novice users. Thirty‑two (32) volunteers are randomly assigned in a completely randomized design with 8 users per layout, and each user completes one timed trial. The company analyzes the between‑layout variation with a one‑way ANOVA. The total sum of squares and treatment (factor) sum of squares are calculated as follows:  SSTotal = 1040 SSTreatment = 480
