Problem 43

Suppose a survey asks, “Do you own any CDs?” Explain  how this could be interpreted in more than one way. Suggest a  way in which the question could be improved.

Step-by-Step Solution:

Step 1 of 5) Suppose a survey asks, “Do you own any CDs” Explain how this could be interpreted in more than one way. Suggest a way in which the question could be improved. Explain Type I and Type II Errors Sample data is used to decide whether or not to reject the statement in the null hypothesis. Because this decision is based on incomplete (sample) information, there is the possibility of making an incorrect decision. In fact, there are four possible outcomes from hypothesis testing. In Other Words Look for key phrases when forming the alternative hypothesis. For example, more than means +; different from means 3 and less than means *. See Table 9 on page 332 for a list of key phrases and the symbols they translate into. Four Outcomes from Hypothesis Testing 1. Reject the null hypothesis when the alternative hypothesis is true. This decision would be correct. 2. Do not reject the null hypothesis when the null hypothesis is true.
