Question Help Refer to the table linked below. Is constructing a conditional distribution by level of education different from constructing a conditional distribution by employment status? If they are different, explain the difference. Click the icon to view the table. Choose the correct answer below. Q A. They are different because constructing a conditional distribution by level of education computes the relative frequency for each employment status, given the individual's level of education. Constructing a conditional distribution by employment status...

The Book of R (Question 20.2) Please answer using R code. Continue using the survey data frame from the package MASS for the next few exercises. The survey data set has a variable named Exer , a factor with k = 3 levels describing the amount of physical exercise time each student gets: none, some, or frequent. Obtain a count of the number of students in each category and produce side-by-side boxplots of student height split by exercise. Assuming independence...
