Question

The manager of a factory collected data in order to analyze the relationship between the number of hours of training a worker receives and

the worker's error rate. The line of best fit for the collected data is y=01 -0.005r where x is the number of hours of training a worker
receives and y is the error rate.
What approximate error rate should the manager expect for a worker who receives 6 hours of training

Answer 1

The approximate error rate the manager should expect for a worker who receives 6 hours of training is 0.07 error rate

Explanation:

The given relation between the number of hours of training a worker receives, x and the worker's error rate y can be presented follows;

y = 0.1 - 0.005·r

Therefore, the approximate error rate the manager should expect for a worker who receives 6 hours of training can be given as follows;

When x = 6 hours, we have

y = 0.1 - 0.005 × 6 = 0.07

The approximate error rate the manager should expect for a worker who receives 6 hours of training is 0.07.

Which is an error rate o 7%
