A research team conducted a study of VARIABILITY in students' test performance. Researchers assumethat individual records are normally distributed with unknown mean and variance. They collected asample of n = 25 test scores with summaries shown below.Sample Mean = X = 75.2 and Sample SD = S = 15Estimate the POPULATION VARIANCE with confidence C = 0.99• Show critical values needed• Evaluate the upper and lower confidence limits.UCL =LCL =Solution

Given that : Sample size (n) = 25 Sample mean = 75.2 S = 15 C = 0.99 By using confidence interval…

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"
Also included in question find estimated variance of errors, estimated variance of slope, and 90% and 95% confidence intervals for slope. Thank you so much
