Answer:

a = 1, b = 2, c = 3

Step-by-step explanation:

$a + \frac{1}{b + \frac{1}{c} } = \frac{10}{7} \\ \\ a + \frac{1}{b + \frac{1}{c} } = 1 + \frac{3}{7} \\ \\ a + \frac{1}{b + \frac{1}{c} } = 1 + \frac{1}{\frac{7}{3} } \\ \\ a + \frac{1}{b + \frac{1}{c} } = 1 + \frac{1}{2 + \frac{1}{3} } \\ \\ equating \: like \: terms \: on \: both \: sides \\ \\ a = 1 \\ \\ b = 2 \\ \\ c = 3$

Answer: B. $H_0:p_1=p_2$

$H_a:p_1>p_2$

Step-by-step explanation:

Let $p_1$ be the proportion of all U.S. adults that smoked in 1995. Let $p_2$ denote the proportion of all U.S. adults that smoked in 2000.

Objective for the study : Whether the proportion of U.S. adults that smoke declined during the 5-year period between the samples.

i.e. $p_1>p_2$

Alternative hypothesis $(H_a)$ is the statement containing population parameter that shows there is significant difference between the groups being tested.

⇒ $H_a:p_1>p_2$

Null hypothesis $(H_0)$ is the statement containing population parameter that shows there is no significant difference between the groups being tested.
