Two salesmen, \(A\) and \(B\), work at a company that arranges different types of holidays: self-catering, hotel and cruise. The table shows, for a random sample of 150 holidays, the number of each type arranged by each salesman.
| Type of holiday | ||||
|---|---|---|---|---|
| Self-catering | Hotel | Cruise | ||
| Salesman | \(A\) | 25 | 38 | 21 |
| \(B\) | 28 | 21 | 17 | |
Test at the \(10\%\) significance level whether the type of holiday arranged is independent of the salesman.
