A reseаrcher wаnts tо cоmpаre the average number оf hours students living in dorms exercise per week to those living off-campus. A random sample of 12 students living in dorms and 14 students living off-campus was taken. The results (in hours per week) are as follows:Dorm Students: 3.5, 4.0, 3.8, 2.9, 3.6, 4.2, 3.7, 3.1, 3.9, 4.1, 3.0, 3.4Off-Campus Students: 2.5, 3.0, 2.8, 3.1, 2.7, 2.9, 2.6, 3.2, 3.0, 2.4, 2.7, 2.5, 2.8, 2.9Using a 0.1 level of significance, test whether there is a significant difference in the average weekly exercise time between students living in dorms and those living off-campus. Clearly define the hypotheses, show all calculations, and state your conclusion.
Welcоme tо the Hоnor Lock Prаctice Quiz! Pleаse reаd through the entirety of this practice assessment. Don't worry though, this is an easy 100%! The purpose of this practice assessment is to help you acclimate to the Honorlock proctoring system. While this assessment is open, you should see the Honorlock tool bar at the bottom of your screen. You can expect to see this on all assessments proctored by Honorlock. This ensures that we can accurately proctor your assessment as well as provide you with information and tools you might need during your assessment, such as your assessment guidelines or an on-screen calculator. In addition, you'll be able to preview your webcam capture and minimize it back to the tool bar. You won't need to display it over your assessment so feel comfortable minimizing it to the tool bar so that it doesn't distract you. Finally, if you wish to reach out to Honorlock Support with a question about the proctoring process, you can click on the message icon to do so. We want to answer any questions you may have about the proctoring experience. However, we cannot answer any questions directly related to your course or assessment.
