The numbers of courses taught per semester by a random sample of university professors are shown in the histogram. Make a frequency distribution for the data. Then use the table to estimate the sample mean and the sample standard deviation of the data set.**Histogram Explanation:**The histogram displays the number of professors versus the number of courses taught per semester. - **Number of courses taught (x-axis):** 1 to 4 - **Number of professors (y-axis):** - 1 course: 3 professors - 2 courses: 20 professors - 3 courses: 27 professors - 4 courses: 15 professors**Frequency Distribution Table:**| x | f ||----|----|| 1 | || 2 | || 3 | || 4 | |- The sample mean is \( \bar{x} = \) [Round to one decimal place as needed.]- The sample standard deviation is \( s = \) [Round to one decimal place as needed.]**Interactive Components:**- View Instructor Tip- Textbook- Calculator- "Next" button to proceedThis exercise is designed to help students understand how to compute descriptive statistics from a graphical data representation.

In this case, x defines the number of courses taught per semester and f is the number of professor…

Use R to determine whether the mean population by census tract in 2016 is higher than the mean population by census tract in 2012. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.
