Chapter 9.1, Problem 30E

To determine

Type I error The probability of Type II error from (a) 0.01, (b) 0.10, (c) 0.89, (d) 0.90, (e) 0.99, so that power is 0.90.

Answer to Problem 30E

The correct option is (b).

Explanation of Solution

Given Information:

Power = 0.90

Formula Used:

  $\text{P}\left(\text{Type}\text{II}\text{erro}r\right)=1-\text{Power}$ .

Calculation:

Find the probability of Type II error. Use the formula $\text{P}\left(\text{Type}\text{II}\text{erro}r\right)=1-\text{Power}$ .

  $\begin{array}{c}\text{P}\left(\text{Type}\text{II}\text{erro}r\right)=1-\text{Power}\\ =1-0.90\\ =0.10\end{array}$

Hence, the correct option is (b).
