# survey data analysis (discrete data)

I did small survey and get such data:

|-------------| Yes | No | Dont_Know |
|-------------|     |    |           |
| Employee    | 60  | 5  | 5         |
| Workers     | 17  | 0  | 1         |
| Businessmen | 71  | 5  | 10        |
| Jobless     | 4   | 30 | 0         |


R code

dt <- data.frame(workers = c("Employee",
"Workers",
"Jobless"),
yes = c(60,17,71,4),
no = c(5,0,5,30),
dont_know = c(5,1,10,0)
)

1. What kind of test I must do, if I want to show, that the Jobless people are often choosing No answer?
