Answer: B.
Step-by-step explanation:
Let be the proportion of all U.S. adults that smoked in 1995. Let 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.
Alternative hypothesis is the statement containing population parameter that shows there is significant difference between the groups being tested.
⇒
Null hypothesis is the statement containing population parameter that shows there is no significant difference between the groups being tested.
⇒
Hence, The hypotheses to test in this problem are
Hence, the correct answer is B.
Answer:
The equation could be used to represent this situation.
Step-by-step explanation:
Given:
Azul bought 10 reams of paper at the store for a total cost of $84 the tax on the purpose was $4.
Now, to find the equation that could be used to represent this situation.
Let the cost of a ream of paper be
Total reams of paper = 10.
The tax on the purpose = $4.
The total cost = $84.
Now, to write an equation to represent this situation:
Therefore, the equation could be used to represent this situation.
