In question 19 of the Application Questions in Chapter 7, we correlated “burnout” scores (X) with absenteeism scores (Y). Using those data: (a) Compute the linear regression equation. (b) Compute the standard error of ...In the typical correlational design, (a) Do we group the scores to summarize them, and if so how? (b) What are the three descriptive statistics we compute for the summary? (a) What two assumptions must you make about the data in order for the standard error of the estimate to be accurate, and what does each mean? (b) How does heteroscedasticity lead to an inaccurate description of the data? We obtain a X = 46.8 (N = 15) which may represent the population where µ = 50 (σx = 11). Using the criterion of .05 and the lower tail of the sampling distribution: (a) What is our critical value? (b) Is this sample in the ...The mean of a population of raw scores is 50 (σx = 18).
