**Educational Website Content: Upper Confidence Interval Calculation**In this exercise, you are tasked with calculating the upper confidence interval of the true population mean from the given data set using a 90% confidence level. Below is the data set provided:| Observation | Data ||-------------|-------|| 1 | 1.02 || 2 | 4.92 || 3 | 1.16 || 4 | 2.98 || 5 | 5.02 || 6 | 7.78 || 7 | 5.76 || 8 | 7.76 || 9 | 9.43 || 10 | 8.11 || 11 | 9.05 |**Instructions:**1. Calculate the sample mean (average).2. Determine the standard deviation of the sample.3. Use the t-distribution to find the critical value for a 90% confidence level.4. Calculate the margin of error.5. Add the margin of error to the sample mean to find the upper confidence interval.*Note: Round your final answer to the nearest hundredth.*Once you have completed your calculations, place your answer in the designated space.**Submission:**Click on "Save and Submit" to record your response.
