The deterioration of many municipal pipeline networks across the country is a growing concern. One technology proposed for pipeline rehabilitation uses a flexible liner threaded through existing pipe. An article reported the following data on tensile strength (psi) of liner specimens both when a certain fusion process was used and when this process was not used. No fusion 2738 2710 2645 2822 2501 3149 3267 3213 3230 2763 m = 10 x = 2903.8 s1 = 281.8Fused 3027 3346 3369 3297 3135 2900 2889 2912 n = 8 y = 3109.4 s2 = 206.1Required:Does the data suggest that the standard deviation of the strength distribution for fused specimens is smaller than that for not-fused specimens?
