Question

An article contained the following observations on degree of polymerization for paper specimens for which viscosity times concentration fell in a certain middle range:

418	420	421	423	425	429	432	435	436
439	445	446	448	452	456	461	464

1.Comment on any interesting features. (Select all that apply.)

a.The data appears to be centered near 438.

b.The data appears to be centered near 428.

c.There is little or no skew.

d.The data is strongly skewed.

e.There are no outliers.

f.There is one outlier.

2.Calculate a two-sided 95% confidence interval for true average degree of polymerization. (Round your answers to two decimal places.)
