Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 30.2 hg < u< 32.0 hg with only 19 sample values, x = 31.1 hg, and s = 1.8 hg? What is the confidence interval for the population mean u? hg < u< hg (Round to one decimal place as needed.) Are the results between the two confidence intervals very different? O A. No, because the confidence interval limits are similar. O B. Yes, because the confidence interval limits are not similar. C. No, because each confidence interval contains the mean of the other confidence interval. O D. Yes, because one confidence interval does not contain the mean of the other confidence interval.
