An instructor at a major research university occasionally teaches summer session and notices that there are often students repeating the class. Out of curiosity, she designs a random sample of students enrolled in summer sessions and counts the number repeating a class. She counts 105 students in the sample, of which 19 are repeating a class. She hypothesizes that, in general, more than10% of students repeat a course. The hypotheses to be tested are:   Select one: H0:p=0.1  vs. Ha:p=0.18 H0:p=0.1  vs. Ha:p≠0.1 H0:p=0.1  vs. Ha:p>0.1 H0:p=0.1  vs. Ha:p>0.18
