## Confidence Interval Construction### Problem Statement:Construct 90%, 95%, and 99% confidence intervals to estimate $\mu$ from the following data. State the point estimate. Assume the data come from a normally distributed population.### Data:- 12.5- 11.6- 11.9- 12.7- 12.5- 11.4- 12.0- 11.7- 11.8- 12.5### Instructions:Use Appendix A Statistical Tables for calculations. Round the standard deviation to 4 decimal places, e.g., 25.3172. Round your answers to 2 decimal places.### Confidence Intervals:- **90% confidence interval:** \[ \underline{\hspace{2cm}} \leq \mu \leq \underline{\hspace{2cm}} \]- **95% confidence interval:** \[ \underline{\hspace{2cm}} \leq \mu \leq \underline{\hspace{2cm}} \]- **99% confidence interval:** \[ \underline{\hspace{2cm}} \leq \mu \leq \underline{\hspace{2cm}} \]### Point Estimate:The point estimate is $\underline{\hspace{3cm}}$.
