De SFU The analgesic effects of music are well known, but most of the studies have been done with adults and most of the music has been classical. You want to know whether children who choose their own music or audiobook to listen to after a surgery experience less pain and whether that depends on a severity of a surgery. To answer this question, you asked children who underwent minor and major surgeries to listen to music or a story of their choice, or to sit with noise-cancelling headphones for 30 minutes and then to point to a pain face that best illustrated their level of pain.

Question 1. Greater than or Less than. Question 2. IS or IS NOT.
Consider the following research questions/study scenarios. For each study, discuss the most appropriate methods for describing the data (graphically and numerically). What statistical method would be most appropriate for addressing the research questions? Be sure to provide a justification of the statistical method. What statistical test is needed, provide appropriate null and research hypotheses. An investigation of the association between drink preferences and the color of teeth is proposed. Subjects will be surveyed as to the type of drink most often consumed (coffee/tea. Juice, caramel-colored soda, water, or milk). A clinical exam will be performed after dental cleaning to determine the color of the teeth (reddish brown, reddish yellow, gray, reddish gray).

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
