**Question 1**Find the mean for the given data:| x | f ||---|---|| 1 | 2 || 2 | 3 || 3 | 5 || 4 | 4 || 5 | 1 || 6 | 4 || 7 | 5 || 8 | 3 || 9 | 2 |**Choices:**- ○ 6.3- ○ 5- ○ 3.1- ○ none of these answers**Explanation:**The table consists of two columns, `x` (the data values) and `f` (the frequencies of these values). To calculate the mean, use the formula:\[\text{Mean} = \frac{\sum (x \times f)}{\sum f}\]Calculate the sum of the products of `x` and `f`, and divide by the sum of the frequencies `f`. Compare the result with the given options to find the correct answer.

For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. 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.
