Use this scenario to answer questions below.

The Collins Research Crew (CRC) is interested in examining thenumber of vape/smoking stores (i.e. stores that sell vaping andcigarette/cigar smoking products) in low-income neighborhoodscompared to other types of neighborhoods. CRC's research questionis, "Do low-income neighborhoods have more vape/smoke shops thanother types of neighborhoods?" Low-income neighborhoods weredefined as those where the median household income is less than theU.S. federal poverty line. Non-low-income neighborhoods are thosethat the median household income is greater than the U.S. federalpoverty line.

CRC employed a team of undergraduate researchers to go out andcount the number of vape/smoke shops in a random selection oflow-income and non-low-income neighborhoods. They define thepopulation as all neighborhoods in King County.

They found a significant difference in the number of vape/smokeshops across neighborhoods. Specifically, low-income neighborhoodshad a greater number of vape/smoke shops compared to non-low-incomeneighborhoods.

Match the null hypothesis, directional hypothesis, andnon-directional hypothesis with their most appropriatestatement.

Null Hypothesis

      [ Choose ]          

There is a relationship between the average number of vape/smokeshops and neighborhood type..          

There is no relationship between the number of vape/smoke shopsand neighborhood type.          

Low-income neighborhoods have more vape/smoke shops thannon-low-income neighborhoods.average.      

Directional Hypothesis

      [ Choose ]          

There is a relationship between the average number of vape/smokeshops and neighborhood type..          

There is no relationship between the number of vape/smoke shopsand neighborhood type.          

Low-income neighborhoods have more vape/smoke shops thannon-low-income neighborhoods.average.      

Non-directional hypothesis

      [ Choose ]          

There is a relationship between the average number of vape/smokeshops and neighborhood type..          

There is no relationship between the number of vape/smoke shopsand neighborhood type.          

Low-income neighborhoods have more vape/smoke shops thannon-low-income neighborhoods.average.      

Given the research question asked in the scenario above, thebest research hypothesis is a non-directional hypothesis.

True OR False
