The sequence shows the majority party of the U.S. Senate after each election for a recent group of years, where \(R\) represents the Republican party and \(D\) represents the Democratic party. Can you conclude that the sequence is not random?

(a) identify the claim and state \(H_{0}\) and \(H_{a}\),

(b) find the critical values,

(c) find the test statistic,

(d) decide whether to reject or fail to reject the null hypothesis,

(e) interpret the decision in the context of the original claim. Use \(\alpha=0.05\).
