Problem 9E

Let $$X_{i}, i=1,2,3,4$$, equal the distance (in yards) that a golf ball travels when hit from a tee, where $$i$$ denotes the index of the $$i$$ th manufacturer. Assume that the distribution of $$X_{i}$$ is $$N\left(\mu_{i}, \sigma^{2}\right), i=1,2,3,4$$, when a ball is hit by a certain golfer. We shall test the null hypothesis $$H_{0}$$ : $$\mu_{1}=\mu_{2}=\mu_{3}=\mu_{4}$$, using three observations of each random variable.

(a) Give a critical region for an $$\alpha=0.05$$ significance level.

(b) Construct an ANOVA table and state your conclusion, using the following data:

(c) What would your conclusion be if $$\alpha=0.025$$ ?

(d) What is the approximate $$p$$-value of this test?
