You intend to estimate a population mean μμ from the following sample. 16.3 19.3 -5.5 -2.8 11.1 15.4 18.2 29.2 2.5 28 0.9 12.1 50 35.5 25.9 26.3 13.5 16 10 10.4 37.5 15.2 27.6 44.6 8.3 26.6 -2.5 8.3 20 15 33.9 -0.2 22.8 14.1 1.1 27.1 13 3.9 23.5 15.4 -0.5 17.4 33.2 28 51.3       Hint: Use the ONE QUANTITATIVE Calculator to find the Mean and Sample Standard Deviation of the data set. Find the 95% confidence interval. Enter your answer as a tri-linear inequality accurate to two decimal places (because the sample data are reported accurate to one decimal place). ___<  μ < ____ Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
