A simple random sample of 15-year old boys from one city is obtained and their weights (in pounds) are listed below. Use a 0.01 significance level to test the claim that these sample weights come from a population with a mean equal to 147 lb. Assume that the standard deviation of the weights of all 15-year old boys in the city is known to be 16.7 lb.  Your scratch paper must show all five steps as demonstrated in the videos or you will not receive credit.             146   140    160    151    134    189    157    144    175    127    164            What is the test statistic? z=[test] (round to 2 decimal places) What are the critical values?  z=+/- [critical] (round to 3 decimal places) What is your conclusion about the claim? [conclusion] s = support the claim r = reject the claim f = fail to reject the claim n = not enough evidence to support the claim

Adjust your camera so that your face, your entire work area, and both hands are fully visible. You must show both your face and hands during the test. The non-mouse hand must always be visible, and if the mouse hand is not visible, the cursor should be moving. Sound must remain on for the entire duration of the test. You need app Camo and the second webcam to show your area.  To turn your smartphone into a webcam, we recommend using the app Camo. It’s compatible with iOS, Android, MAC, and PC. However, Honorlock does have some other suggestions: read through the Use your smartphone as a webcam section located in the Setting Up A Side-Angle Camera guide. Here’s a detailed video that will walk you through setting up Camo on your smartphone and Mac/PC (ignore the ad part of the video regarding the software Producer): Video. Here is an image adequate desk view during testing:       Example of Bad testing Camera Angle: will result in a zero on the test, due to not showing hands and working during the exam)   Grading Criteria (35 points total) 100 % work are visible and computer screen – 20 points Face visible – 5 points Two hands visible – 10 ponts Type “Camera Angle” in the answer box
