Explain the chances of type i error

Reference no: EM131373442

If you look at the power curve or the OC curve of a two-tailed test, you see that there is no region that represents instances of type I error, whereas there are large regions that represent instances of type II error.

Does this mean that there is no chance of type I error? Think carefully, and explain the chances of type I error and the role of α in a two-tailed test.
