A test statistic for one of the tests in this unit is given, along with information about degrees of freedom. Give the p-value a indicate whether the results are significant at the 5% level. An analysis of variance test with F-statistic = 8.71 and df -numerator = 3 and df -denominator = 17 Round your answer to four decimal places. p-value = i

In a t-test for paired samples, the one value that compares, for each person, her or his two measurements is called the                                   .       Difference score     Deviation score     Standard deviation     Standard difference

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"

Consider the following data: −10, −10, 0, 3, −10, 3, 3  Step 1 of 3: Calculate the value of the sample Variance. Round your answer to one decimal place. Step 2 of 3: Calculate the value of the sample deviation. Round your answer to one decimal place. Step 3 of 3: Calculate the value of the range.
