a. Use the accompanying output from the ?Bootstrap Confidence Interval for One Proportion? Shiny app to report a 95% bootstrap confidence interval for the population proportion who would reply ?No? to the question. Interpret the confidence interval in context.

b. SodaHead provides summaries for anonymous and voluntary responses to survey questions.

Does the proportion of respondents who reply ?No? to the question in an anonymous and voluntary situation tend to underestimate or overestimate the actual population proportion of interest? Explain.
