Sure! Here is a transcription for an educational website:---**Study on Part-Time Student Course Loads**A survey was conducted among fifty part-time students to determine how many courses they were taking during the current term. The incomplete data is presented below:### Table 1.13: Part-time Student Course Loads| # of Courses | Frequency | Relative Frequency | Cumulative Relative Frequency ||--------------|-----------|--------------------|------------------------------|| 1 | 30 | 0.6 | || 2 | 15 | | || 3 | | | |**Assignments:**a. Fill in the blanks in Table 1.13.b. What percent of students take exactly two courses?c. What percent of students take one or two courses?--- **Explanation:**- **Frequency**: Refers to the number of students taking a specific number of courses.- **Relative Frequency**: Calculated as the frequency divided by the total number of students surveyed (50).- **Cumulative Relative Frequency**: Represents the accumulation of relative frequencies across categories, indicating the proportion of students taking up to a certain number of courses.Use the above definitions to analyze and complete the table, and answer the questions that follow.
