**Constructing a Confidence Interval for the Population Mean**To construct a confidence interval for the population mean $\mu$ using the t-distribution, follow these steps. Assume the population is normally distributed.**Given:**- Confidence level ($c$): 0.90- Sample mean ($\bar{x}$): 13.9- Sample standard deviation ($s$): 0.73- Sample size ($n$): 19**Goal:**- Calculate the confidence interval.**Instructions:**1. **Identify the critical value** for the t-distribution using the confidence level and degrees of freedom ($df = n - 1 = 18$).2. **Calculate the standard error** of the mean: \[ SE = \frac{s}{\sqrt{n}} \]3. **Construct the confidence interval**: \[ \bar{x} \pm (t \times SE) \]**Note:** Round the final answers to one decimal place as needed.**Additional Resources:**- Use the options "Help me solve this," "View an example," or "Get more help" for guided instruction and further understanding.**Technical Note:**Ensure your device's temperature remains optimal to facilitate smooth calculations.
