In a sample of 176 students at an Australian university that introduced the use of plagiarism-detection software in a number of courses, 51 students indicated a belief that such software unfairly targets students. Does this suggest that a majority of students at the university do not share this belief? Test appropriate hypotheses at level 0.05. (Let p be the proportion of students at this university who do not share this belief.) LAUSE SALT State the appropriate hypotheses. O Ho: P = 0.50 H₂:D < 0.50 Ho: p=0.50 H:D > 0.50 Ho: D > 0.50 H₂: D-0.50 Ho: p=0.50 H₂: D = 0.50 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) 2- P-value=0.0000 What can you conclude? Reject the null hypothesis. There is sufficient evidence that more than 50% of all students do not share the belief that the plagiarism-detection software unfairly targets students. O Reject the null hypothesis. There is not sufficient evidence that more than 50% of all students do not share the belief that the plagiarism-detection software unfairly targets students. O Do not reject the null hypothesis. There is sufficient evidence that more than 50% of all students do not share the belief that the plagiarism-detection software unfairly targets students. O Do not reject the null hypothesis. There is not sufficient evidence that more than 50% of all students do not share the belief that the plagiarism-detection software unfairly targets students. ✓
