Christopher is a student and he is interested in knowing whether the nine Star Wars movies are equally popular on campus. He randomly surveys 882 students and gets the following results
Movie Count

Episode V - The Empire Strikes Back 115
Episode VI - Return of the Jedi 104
Episode I - The Phantom Menace 87
Episode II - Attack of the Clones 81
Episode III - Revenge of the Sith 122
Episode VII - The Force Awakens 91
Episode VIII - The Last Jedi 103
Episode IX -The Rise of Skywalker 73
where the count indicates the number of students in the sample who said the corresponding movie was their favorite
a. What statistical test can Christopher use to answer his question? What are the conditions of this test? Are they satisfied?
b. Write down the hypotheses for determining whether the nine Star Wars movies are equally popular on campus. Carry out the hypothesis test, calculate the p-value of the test and make a conclusion at a 0 .01 significance level.
c. After looking at your hypothesis test in part b., another student is confused as to why the p-value is not multiplied by two (as was done in other statistical tests covered in the course). Briefly explain why the p-value you calculated above is not multiplied by two and why the right-tail probability is calculated instead of the left tail.
