nd tattoos were big personal grooming red​ flags?  b. Construct a​ 99% confidence interval estimate of the proportion of all human resource professionals believing that body piercings and tattoos are big personal grooming red flags. round to 3 decimal points  c. repeat b using 80% confidence  d. Compare the confidence intervals from parts (b) and (c) and identify the interval that is wider. Why is it wider? A. The 99% confidence interval is wider than the 80% confidence interval. A confidence interval must be wider in order to be less confident that it captures the true value of the population proportion. B. The 99% confidence interval is wider than the 80% confidence interval. A confidence interval must be wider in order to be more confident that it captures the true value of the population proportion. C. The 80% confidence interval is wider than the 99% confidence interval. A confidence interval must be wider in order to be more confident that it captures the true value of the population proportion. D. The 80% confidence interval is wider than the 99% confidence interval. A confidence interval must be wider in order to be less confident that it captures the true value of the population proportion.
