Transcribed Image Text:**Sample Data for Population Mean Estimation**
Use the following sample to estimate a population mean, denoted as \( \mu \).
Sample Data:
- -0.4
- 41.3
- -2.6
- 7.6
- 33.5
- 22.7
- 33.1
- 47.1
- 13.8
- -8.6
- 36.8
**Task:**
Assuming the population is normally distributed, calculate the 90% confidence interval for the population mean. Your answer should be in the form of an open interval (i.e., parentheses) and accurate to two decimal places.
90% C.I. = \( \_\_\_\_\_\_ \)
