A college chemistry instructor thinks the use of embedded tutors will improve the success rate in introductory chemistry courses. The passing rate for introductory chemistry is 73%. During one semester, 200 students were enrolled in introductory chemistry courses with an embedded tutor. Of these 200 students, 162 passed the course. The instructor carried out a hypothesis test and found that the observed value of the test statistic was 2.55. The p-value associated with this test statistic is 0.0054. Explain the meaning of the p-value in this context. Based on this result, should the instructor believe the success rate has improved? State the hypotheses that were used for the test Choose the correct answer below. OA. Ho: p=0.73 and Ha: p>0.73 OB. Ho: p<0.73 and Ha: p>0.73 OC. Ho p=0.73 and Ha: p<0.73 OD. Ho: p>0.73 and Ha: p<0.73 OE. Ho: p=0.73 and Ha: p# 0.73 Explain the meaning of the p-value in this context. Select the correct choice below and fill in the answer box within your choice. (Type an integer or a decimal. Do not round.) OA. The probability of 162 or more introductory chemistry students passing out of a random sample of 200 students is OB. The probability of 162 or fewer introductory chemistry students passing out of a random sample of 200 students is assuming the population proportion is 0.73. , assuming the population proportion is less than 0.73. OB. Ho: p<0.73 and Ha: p>0.73 OC. Ho: p=0.73 and Ha: p<0.73 OD. Ho: p>0.73 and Ha: p<0.73 O E. Ho: p=0.73 and Ha: p 0.73 Explain the meaning of the p-value in this context. Select the correct choice below and fill in the answer box within your choice. (Type an integer or a decimal. Do not round.) OA. The probability of 162 or more introductory chemistry students passing out of a random sample of 200 students is OB. The probability of 162 or fewer introductory chemistry students passing out of a random sample of 200 students is OC. The probability of 162 or more introductory chemistry students passing out of a random sample of 200 students is OD. The probability of 162 or fewer introductory chemistry students passing out of a random sample of 200 students is In this situation, the p-value small, so the instructor believe the success rate has improved. assuming the population proportion is 0.73. assuming the population proportion is less than 0.73. assuming the population proportion is greater than 0.73. , assuming the population proportion is 0.73.
