# How can the probability of a type I error be reduced?

##### 1 Answer

By lowering the

#### Explanation:

The probability of a Type I error is *outside* the C.I. for

The chance of a Type I error occurring is directly related to the width of our C.I. for the parameter. If we want to decrease the chance of Type I error, we increase the width of the C.I., which means decreasing the area we wish to have in the tails, and that is simply done by decreasing the value we use for

Our *equal* to the total area in the tail(s). Simply put, that means
