Even without assuming bias, the data indicates distinct patterns in how different age groups responded to the proposed speed limit change. The majority of respondents in the 30-34 age group chose not to respond, totaling 55 individuals out of 75. Meanwhile, those aged 25-29 showed strong support for the change, with 80 out of 115 respondents voting in favor. Similarly, the youngest age group, 20-24, also leaned towards approval, with 45 out of 95 participants voting yes. Despite assuming no bias, the non-response from the 30-34 age group significantly influences the overall perception of support for the speed limit change. With 69% of this age group opting not to provide an answer, their lack of participation skews the results towards a higher proportion of non-supportive responses relative to other age groups. Consequently, even in the absence of assumed bias, the 30-34 age group's non-response has a notable impact on the perceived level of support for the change, highlighting the importance of considering all demographic responses to accurately gauge public opinion. use this to paraphrase it together as well
