A teacher selects a random sample of 56 students from her large high school. For each student, she records the length of their hair and whether they play a sport. She would like to know if there is convincing evidence that hair length is associated with playing a sport. Let = 0.05. What are the hypotheses for this test? H0: Hair length is not independent of playing a sport. Ha: Hair length is independent of playing a sport. H0: Hair length is independent of playing a sport. Ha: Hair length is not independent of playing a sport. H0: There is an association between hair length and playing a sport. Ha: There is no association between hair length and playing a sport. H0: The proportion of students with differing hair lengths is not the same if they play sports. Ha: The proportion of students with differing hair lengths is the same if they play sport
