A news article reported that the college students who have part-time jobs work an average of 15 hours per week. The staff of a college newspaper thought that the average might be different from 15 hours per week for their college. Data were collected on the number of hours per week for a random sample of students at the college who have part-time jobs. The test were used to test the hypotheses: Ho: u=15 H: u+ 15. where u is the mean number of hours worked per week for students at the college with part-time jobs. The results of the test are shown in the table. Sdf t-stat p-value 13.755 3.535 25 -1.761 0.090 Assuming all conditions for inference were met, a 95% confidence interval for u is: 13.755 + ME where ME is the margin of error. What is the ME ?
