Question
For the entire school, which was more popular, water slides or roller skating?
34% of the 6th graders and 50% of the 7th graders want to go to the water slides. What percentage of the 8th graders want to go to the water slides? Does there seem to an association between grade level and field trip choice? If this trend continued, would you expect 9th graders to prefer the water slides or roller skating? Explain your answer.
6. Middle school class representatives conducted a poll during lunch to see which activity students wanted for their year-end party. The results are shown in this relative frequency table: 6th grade 7th grade 8th grade Total Water slides 0.17 0.15 0.14 0.46 Roller skating 0.33 0.15 0.06 0.54 Total 0.50 0.30 0.20 1.0Explanation / Answer
As per data given roller skating is more popular because roller skating has got 0.54 votes compared to water slide - which got 0.46 votes
For 8th graders
total is 0.20
out of which 0.14 wants to go for water slides
so, it is (0.14/0.20)*100 = 70 % wants to go for water slides from 8th graders.
Yeah, there is association between grade level and field trip choice. As grades are increasing, graders are prefering water slides more than roller skating. in 6th grade, it was 34%, 7th it was 50% and 8th it was 70%. so, it is increasting trend for water slides.
If this trend continue, 9th graders prefer water slides. Reason is higher graders prefer water slides more
