Sergeeva-Olga [200]

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.

⇒ H_0:p_1=p_2

Hence, The hypotheses to test in this problem are

H_0:p_1=p_2

H_a:p_1>p_2

Hence, the correct answer is B. H_0:p_1=p_2

H_a:p_1>p_2
