A study was done to assess the ash content in peat moss used for textile fiber. High ash content affects the quality of the textile. The following data are measurements of the percentage of ash by weight. 0.5 1.8 4.0 1.0 2.0 1.1 1.6 2.3 3.5 2.2 2.0 3.8 3.0 2.3 1.8 3.6 2.4 0.8 3.4 1.4 1.9 2.3 1.2 1.9 2.3 2.6 3.1 2.5 1.7 5.0 1.3 3.0 2.7 1.2 1.5 3.2 2.4 2.5 1.9 3.1 2.4 2.8 2.7 4.5 2.1 1.5 0.7 3.7 1.8 1.7 We know that the data are somewhat skewed. Does this affect the accuracy of the conclusions in 99% confidence interval and hypothesis that the mean is less than 2.70(α = 0.01)? Hint: think about the sample size
