Question

Test the sequence for randomness. Use ? = 0.05.

(a) What is the level of significance?

State the null and alternate hypotheses.

H_o: The symbols are not randomly mixed. H₁: The symbols are randomly mixed.H_o: The symbols are randomly mixed. H₁: The symbols are not randomly mixed. H_o: The symbols are not randomly mixed. H₁: The symbols are not randomly mixed.H_o: The symbols are randomly mixed. H₁: The symbols are randomly mixed.

(b) Find the sample test statistic R, the number of runs.

(d) Conclude the test.

At the ? = 0.05 level, we reject the null hypothesis and conclude the data are statistically significant.At the ? = 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant. At the ? = 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant.At the ? = 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant.

(e) Interpret your conclusion in the context of the application.

Reject the null hypothesis, there is sufficient evidence that the sequence of party affiliation for U.S. House of Representatives is not random.Fail to reject the null hypothesis, there is sufficient evidence that the sequence of party affiliation for U.S. House of Representatives is not random.
