Problem 10.124

The data in the following table give readings in foot-pounds of the impact strength of two kinds of packaging material, type A and type B. Determine whether the data suggests a difference in mean strength between the two kinds of material. Test at the = .10 level of significance. A B 1.25 .89 1.16 1.01 1.33 .97 1.15 .95 1.23 .94 1.20 1.02 1.32 .98 1.28 1.06 1.21 .98 yi = 11.13 y = 1.237 y2 i = 13.7973 yi = 8.80 y = .978 y2 i = 8.6240
