Lighting  ——— The webcam requires adequate lighting to do its job.  If the student’s visibility becomes an issue, a proctor may pause the exam and work with you to resolve it.  Visibility of both yourself and your screen is mandatory.  Please be mindful that for the system to work, adequate lighting is necessary.    By doing this Honorlock can more easily verify the student’s integrity while doing their exam.  Have both you and your screen clearly visible at all times.   Question:  Proper lighting is necessary for you to see your exam on your computer screen

Exam Space ——— The exam space should be free of papers, objects, and electronic devices.  These obstructions have the potential of triggering AI alerts, and your exam may be paused while the proctor (a real person) addresses concerns.  Of particular gravity are cell phones, imaging devices, headphones, and the list goes on.  Do yourself a favor, clear all such devices from your desk space, and turn them off.  If they are triggered to operate, Hororlock may well respond.   Question:  What may be on your desk?

Introduction ——— This short “infoquiz” is designed to inform you about how to successfully take an online proctored exam with Honorlock.  It is not meant to assess, but rather to impart an understanding of the process so that assessments go smoothly.  Indeed, for the majority of students, a proctored exam with Honorlock is a straightforward process that is simple and almost invisible at best.  But for a few students, it can cause frustration if they are not informed of online exam “best practices.”  And that is what this “Infoquiz” is all about.   Please note that this Infoquiz is to inform, not assess; therefore, regardless of the answers given, the bonus points discussed in the Introductory Video will be given.   Question:  For most students, taking an online proctored quiz is a simple process.

An automotive researcher wanted to estimate the difference required to come to a complete stop while traveling 40 miles per hour on wet versus dry pavement. Because car type plays a role, the researcher used eight different cars with the same driver and tires.  The braking distance (in feet) on both wet and dry pavement is shown in the table below. Conduct the appropriate hypothesis test to determine if the braking distance on the wet surface is longer from the braking distance on the dry surface. Use a 0.05 level of significance.  Note:  a normal probability plot of the data indicate that the differences are approximately normally distributed with no outliers.  This is a matched pairs problem.   Car 1 2 3 4 5 6 7 8 Wet 106 100 108 111 105 105 110 107 Dry 71 68 74 73 75 75 75 81   a. 

The American Federation of Teachers, publishes an annual salary report. In 2003, a sample of 51 teachers in California had mean salary with $56, 690 and a standard deviation of $9,000.  In Michigan of the same year, the mean salary for 61 teachers was $52, 000 with a standard deviation of $6000.  Test the hypothesis that the mean salary of teachers in California is greater than the mean salary of the teachers in Michigan.  Use a 0.05 significance level. We will assume that the California teachers are group 1.   a.
