suppose there are two types of people: high-ability and low-ability. a particular diploma costs a high-ability person $8,000 and costs a low-ability person $20,000. firms wish to use education as a screening device where they intend to pay $25,000 to workers without a diploma and $k to those with a diploma. in what range must k be to make this an effective screening device?

Respuesta :

The range that k must be to make this an effective screening device is "33000<=K<=45000".

What does range mean?

In statistic, range of a data, refers to difference between the largest and smallest values. Range is often the result of subtracting the sample maximum and minimum which is expressed in the same units as the data.

It is also size of the smallest interval which contains all the data and provides an indication of statistical dispersion. As its depends on two of  observations, it is most useful in representing the dispersion of small data sets.

High-ability range:

= 8000 + 25000

= 33000

Low-ability range:

= 20000 + 25000

= 45000.
