b) criterion validity
Explanation:
Criterion validity: In research methods & statistics, the term "criterion validity" is also referred as "concrete validity" and is described as the degree to which a particular measure is associated with a particular outcome. There are mainly two distinct types of criterion validity including predictive as well as concurrent validity.
Criterion validity is being helpful for the tests or study that measures behavior in any given scenario.
In the question above, the given statement signifies the "criterion validity".
Worker at $12 per hour, producing 16 pounds of candy per hour
Machine with $5 per hour operating cost, producing 10 pounds of candy per hour
Machine with $8 per hour operating cost, producing 14 pounds of candy per hour
To determine which investment produces a $5 hourly profit for a candy shop, earning $1 profit per pound of candy, we have to analize each option.
1- Worker at $10 per hour, producing eight pounds of candy per hour. This option results in a $2 loss per hour, since the earnings are lower than the costs (8-10= -2).
2- Worker at $12 per hour, producing 16 pounds of candy per hour. This one results in a $4 profit, as the cost is lower than the earnings (16-12= 4).
3- Machine with $5 per hour operating cost, producing 10 pounds of candy per hour. Here we have a $5 profit, as the cost is of $5 and the earnings are of $10 (10-5= 5).
4- Machine with $8 per hour operating cost, producing 14 pounds of candy per hour . In this option, we have a $6 profit (14-8= 6).
So, the investment that produces a $5 hourly profit for a candy shop earning $1 profit per pound of candy is the third option, that is, a machine with $5 per hour operating cost, producing 10 pounds of candy per hour.
