**Frequency Distribution for Course Data**The numbers of courses taught per semester by a random sample of university professors are illustrated in the histogram below. We aim to create a frequency distribution table based on this data and use it to estimate the sample mean and sample standard deviation.**Histogram Explanation**- **X-axis**: Represents the number of courses taught (ranging from 1 to 4).- **Y-axis**: Shows the frequency of professors who teach those numbers of courses.- **Bars**: - 1 course: Frequency is 3 - 2 courses: Frequency is 20 - 3 courses: Frequency is 24 - 4 courses: Frequency is 16**(a) Frequency Distribution Table**| x | f ||---|----|| 1 | 3 || 2 | 20 || 3 | 24 || 4 | 16 |**Calculations**- **Sample Mean (\(\bar{x}\))**: Calculate the average number of courses taught.- **Sample Standard Deviation (s)**: Measure the variation or dispersion of the number of courses.The calculations will be rounded to one decimal place as needed.
