### Confidence Interval Estimation and Comparison for Newborn WeightsHere are summary statistics for randomly selected weights of newborn girls:- Sample size (n): 173- Sample mean (x̄): 30.6 hg- Sample standard deviation (s): 6.1 hgConstruct a confidence interval estimate of the mean using a 95% confidence level. Are these results very different from the confidence interval 30.1 hg < μ < 32.3 hg based on a different set of 12 sample values with:- Sample mean (x̄): 31.2 hg- Sample standard deviation (s): 1.8 hg?#### Confidence Interval CalculationTo construct the confidence interval for the population mean μ, use the formula for the confidence interval:\[CI = \bar{X} \pm Z \left(\frac{\sigma}{\sqrt{n}}\right)\]Where:- \(\bar{X}\) is the sample mean- \(Z\) is the Z-value from the standard normal distribution (Z-score for 95% confidence is approximately 1.96)- \(\sigma\) is the sample standard deviation- \(n\) is the sample size\( \text{hg} < \mu < \text{hg} \)(Round to one decimal place as needed.)#### Comparison QuestionAre the results between the two confidence intervals very different?**Answer Choices:**- **A.** No, because each confidence interval contains the mean of the other confidence interval.- **B.** Yes, because the confidence interval limits are not similar.- **C.** Yes, because one confidence interval does not contain the mean of the other confidence interval.- **D.** No, because the confidence interval limits are similar.### Detailed Explanation of Graphs or DiagramsThere are no graphs or diagrams provided in the text to describe. The content primarily focuses on statistical computation and comparison of confidence intervals.For better understanding, a diagram illustrating the overlapping (or not) of the two confidence intervals could be helpful. This would visually represent whether the intervals share common values or if they are significantly different.### SummaryThis exercise helps in understanding how to compute and compare confidence intervals using sample statistics. By evaluating whether the given intervals overlap or contain each other's means, one can conclude the similarity or difference between the two intervals with respect to the population parameter.

We have developed a new drug used to reduce fever and want to test its efficacy. Ten ER patients who are running a fever agree to take the new drug instead of the traditional treatment. Their temperatures are taken before the drug is administered and 30 minutes after taking the drug. The results are recorded in the Excel file below. Use the data to construct and interpret a 99% confidence interval for the mean change in temperatures of patients after taking this drug using Excel. Be sure to include any explanation necessary along with a sentence that explains what the interval means.
