Answer:

decreases

Step-by-step explanation:

H_0 : New road signs are equally visible

H_α: New road signs are more visible Power

Probability to reject the null hypothesis H_0, when H_0 is false.  

If the level of significance is smaller, then we are less likely to reject the null hypothesis and thus the power decreases.
