The mtcars data frame contains 11 different variables (including its horsepower, hp, and its miles per gallon, mpg) recorded on 32 different models of car. Treating this data frame as your population, which expression would you use to draw a random sample of size five without replacement, where each car is equally likely? Choice 1 of 4:mtcars %>% rep_slice_sample(n = 5, replace = FALSE, reps = 5) Choice 2 of 4:mtcars %>% slice_sample(n = 5, replace = FALSE) Choice 3 of 4:mtcars %>% rep_slice_sample(n = 5, replace = TRUE) Choice 4 of 4:mtcars %>% slice_sample(n = 5, replace = FALSE, weight_by = hp)
