In the PDA research described in Problem 15, one of the outcome variables was mean airway pressure
Question:
In the PDA research described in Problem 15, one of the outcome variables was mean airway pressure (measured in cm H2O) seven days after birth—a measure of respiratory status. The data on this outcome are summarized in the accompanying table.
d. Use the Tukey-Kramer method to locate any significant differences between pairs of means. (Use α = .05.)
In Problem 15
a. Suppose that an ANOVA is to be performed to compare the average birth weight for the different treatment groups. State precisely the ANOVA model. Is treatment group a fixed-effects factor or a random-effects factor?
b. Using the summary statistics given in the table, determine the ANOVA table for the model in (a).
c. Test whether the three treatment groups differ significantly in mean birth weights.
