8.4. 2. In a survey of

210

males ages 20 to 24,

38%

were neither in school nor working. In a survey of

220

females ages 20 to 24,

45%

were neither in school nor working. These samples are random and independent. At

α=0.06,

can you support the claim that the proportion of males ages 20 to 24 who were neither in school nor working is less than the proportion of females ages 20 to 24 who were neither in school nor working? Complete parts (a) through (e) below.

(a) Identify the claim and state

and

Ha.

The claim is "the proportion of males ages 20 to 24 who were neither in school nor working is

(1)

the proportion of females ages 20 to 24 who were neither in school nor working."

Let

and

be the two population proportions for males and females, respectively. State

and

Ha.

Choose the correct answer below.
