Consider the data from Exercise 10.5.10. Suppose the Usual Care group is excluded and comparison is made only between the first three treatments: the two types of real acupuncture and the simulated acupuncture. Here is computer output for a chi-square test to compare the three groups.
X-squared = 1.57, df = 2, p-value = 0.4551
(a) If α = 0.05, what is your conclusion regarding H0?
(b) Write a sentence that combines the conclusion from 10.5.10 and that from 10.5.11(a).
