Solution
An alpha level is the probability of a type I error, or you reject the null hypothesis when it is true. A related term, beta, is the opposite; the probability of rejecting the alternate hypothesis when it is true.
The smaller the alpha level, the smaller is the area where we would reject null hypothesis.
Hence increasing the risk of a type I error would be the choice for answer.
