Question
In April 2010,
45%
of the unemployed had been out of work longer than six months. Policy makers felt that this percentage declined during 2010 as the job market improved. To test this theory, a random sample of
200
unemployed people wasselected, and it was found that
67
had been out of work for more than six months. Using
α=0.10,
answer parts a through c below.

Transcribed Image Text:**Hypothesis Testing Example**
In April 2010, 45% of the unemployed population had been out of work for longer than six months. Policy makers speculated that this percentage declined during 2010 as the job market improved. To evaluate this hypothesis, a random sample of 200 unemployed individuals was selected, revealing that 67 had been out of work for more than six months. Using a significance level (\(\alpha\)) of 0.10, parts a through c provide insight into this matter.
**a. Determining Proportional Changes in Long-term Unemployment**
What conclusions can be drawn regarding the proportion of the unemployed who have been out of work for over six months?
**Task: Determine the Null and Alternative Hypotheses**
Select the correct answer below:
- **A.** \( H_0: p > 0.45 \)
\( H_1: p \leq 0.45 \)
- **B.** \( H_0: p \leq 0.45 \)
\( H_1: p > 0.45 \)
- **C.** \( H_0: p \geq 0.45 \)
\( H_1: p < 0.45 \)
- **D.** \( H_0: p = 0.45 \)
\( H_1: p \neq 0.45 \)
