Snowmobiles in the park Yellowstone National Park surveyed a random sample of $1526$ winter visitors to the park. They asked each person whether they owned, rented, or had never used a snowmobile. Respondents were also asked whether they belonged to an environmental organization (like the Sierra Club). The two-way table summarizes the survey responses.

Do these data provide convincing evidence of an association between environmental club membership and snowmobile use for the population of visitors to Yellowstone National Park? Follow the four-step process.

The information on environmental clubs is shown in the below table which was got from two-way table survey responses:

The distribution of a category variable is displayed using pie charts and bar graphs. Any set of quantities measured in the same units can be compared using bar graphs. It's a good idea to ask yourself, "What do I see?" when looking at any graph.

The following is a conditional distribution of now mobile use by winter visitors to Yellowstone National Park to members of the environment club:

The conditional distribution of snowmobile use by winter visitors to Yellowstone National Park among non-members of environmental clubs is shown below.

The following is a conditional distribution comparison table:

Step III-Achieve: We'll create a side-by-side bar graph to compare the perspectives of environmental club members and non-members:

Step IV-CONCLUDE: As a result, about $70\%$of environment club members have never used a snowmobile ($69.5$percent vs $36.4\%$), and only about$5\%$of environment club members possess a snowmobile ($5.2$percent vs $22.9$percent ). Snowmobile rentals make up roughly $41\%$of non-members of the Environment Club ($25.3$percent vs $40.7$percent ).

As a result, over$70\%$of environment club members have never used a snowmobile, whereas only about $5\%$of environment club members possess a snowmobile. Snowmobile rentals make up roughly $41\%$of non-members of the Environment Club.
