The data is strongly skewed. The data appears to be centered near 428. There are no outliers. The data appears to be centered near 438. There is little or no skew. (b) Is it plausible that the given sample observations were selected from a normal distribution? Yes No (c) Calculate a two-sided 95% confidence interval for true average degree of polymerization. (Round your answers to two decimal places.) Does the interval suggest that 440 is a plausible value for true average degree of polymerization? Yes No Does the interval suggest that 456 is a plausible value? Yes No
