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"

After his father bought him goggles, Jeffery swam the 25-yard freestyle 15 times. After the 15 swims, Jeffery's mean time was 16 seconds and sample standard deviation was 2 seconds. His father thought the goggles helped Jeffery swim faster. Test his father's hypothesis using a 5% level of significance. Assume that the sample of measurements are from a normally distributed population. 6.30 suburb.
