C1 The data appears to be centered near 429. C] There is little or no skew. [:1 There is one outlier. C] There are no outliers. C1 The data appears to be centered near 439. (b) Is it plausible that the given sample observations were selected from a normal distribution? 0 Yes ONO (c) Calculate a two-sided 95% confidence interval for true average degree of polymerization. (Round your answers to two decimal places.)
