At a manufacturing company for medical supplies, machines produce parts used in highly specialized lasers. Company researchers are testing a new machine designed to improve the precision of the parts. The null hypothesis is that the new machine does not improve the precision. For the researchers, the more consequential error would be that the new machine actually improves the precision, but the test does not detect the improvement. Which of the following should the researchers do to avoid the more consequential error?
A) Increase the significance level to increase the probability of a Type I error.
B) Increase the significance level to decrease the probability of a Type I error.
C) Decrease the significance level to increase the probability of a Type I error.
D) Decrease the significance level to decrease the probability of a Type I error.
E) Decrease the significance level to decrease the standard error.
