**Calculating the Upper Confidence Interval**This exercise involves calculating the upper confidence interval of the true population mean from a given data set using a 90% confidence level. The data is presented in a tabular format as follows:| Observation | Data ||-------------|-------|| 1 | 4.46 || 2 | 2.26 || 3 | 9.35 || 4 | 8.99 || 5 | 8.09 || 6 | 2.92 || 7 | 9.03 || 8 | 3.19 || 9 | 1.98 || 10 | 3.56 || 11 | 5.21 |**Instruction:** Round your answer to the nearest hundredth and place your answer in the provided text box.To submit your answer, click "Save and Submit."The exercise is part of a statistical analysis section, typically involving steps such as:1. Calculating the sample mean.2. Determining the standard deviation.3. Applying the formula for the confidence interval using the t-distribution for small sample sizes or the z-distribution for large ones.Please ensure all calculations are performed accurately to achieve the correct upper interval value.
