I can't seem to figure out how to obtain the type 2 error rate from this question.

A researcher is conducting a hypothesis test to determine whether people can be trained to be better at detecting when someone's lying. He found training on average an increase in probability of detection by 0.06, data's normally distributed and standard error of training effect of the population is 0.135. If type I error rate is 0.05 what's your type II error rate?

Any help greatly appreciated! Thank you
