The data (cough improvement scores) for the 33 children in the DM dosage group and the 35 children in the honey dosage group are reproduced in the table below. In Exercise 8.23, you used a comparison of two means to determine whether "honey may be a preferable treatment for the cough and sleep difficulty associated with childhood upper respiratory tract infection." The researchers also want to know if the variability in coughing improvement scores differs for the two groups. Conduct the appropriate analysis, using α = .10.
