Answer 1

Yes, SAT coaching classes can help students improve their test scores. To analyze the data of the students who completed the coaching class, we would use the one sample t-test. The correct answer will be one sample t test.

Step-by-step explanation:

Yes, SAT coaching classes can be effective in helping students improve their test scores. These classes provide students with strategies, practice materials, and guidance on the format and content of the SAT exam. By learning these strategies and practicing with the materials, students can become familiar with the exam and develop skills to answer questions more effectively.

However, the effectiveness of coaching classes can vary depending on the quality of the program and the effort and dedication of the student.

To analyze the data of the four randomly selected students who completed the SAT coaching class, we would need to use the one sample t-test.

This test compares the mean score of the four students after the coaching class to a hypothesized mean score and determines if there is a significant difference. The one sample t-test is appropriate when we have one group of subjects and we want to compare their scores to a known or hypothesized value.
