Answer these question ### Understanding Confidence Intervals with Stock Prices**Scenario Description:**A random sample of closing stock prices in dollars for a company in a recent year is listed below. Assume the standard deviation (σ) is $2.13. The task is to construct the 90% and 99% confidence intervals for the population mean, interpret the results, and compare the widths of the confidence intervals.**Sample Data:**- 21.37- 18.27- 22.77- 20.79- 16.01- 21.32- 17.67- 18.31- 20.63- 15.51- 19.39- 20.04- 16.24- 17.98- 17.53- 21.81**Instructions:**- Construct the 90% confidence interval.- (Round to two decimal places as needed.)**Placeholder for Input:**- The 90% confidence interval is $(\square, \square)$.**Resources:**- Help Me Solve This- View an Example- Get More Help**Note:**This exercise helps in understanding how to calculate and interpret confidence intervals, which are critical in statistical analysis to estimate the range in which a population parameter lies, based on sample data.**Footer:**- Copyright © 2021 Pearson Education Inc.

Arandom sample of the closing stock prices in dollars for a company in a recent year is listed below. Assume that o is $2.13. Construct the 90% and 99% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. 22.77 20.79 16.01 21.32 17.67 18.31 21.37 18.27 19.39 20.04 16.24 17.98 17.53 21.81 20.63 15.51 The 90% confidence interval is ($ S) (Round to two decimal places as needed.)
