K must be in range <u>**$45000 ≤ k ≤ $53000 **</u>to make this an effective screening device.

**Step-by-step explanation:**

In order for the screening device to be effective, the range of k must be such that, it is more than the pay of a worker without diploma. The extra amount must at least be equal to the cost of diploma

So the value of k must be in range from (35000 + 10000) to (35000 + 18000)

Hence,

<u>**$45000 ≤ k ≤ $53000**</u>
