How quickly do synthetic fabrics such as polyester decay in landfills? A researcher buried polyester strips in the soil for different lengths of time, then dug up the strips and measured the force required to break them. Breaking strength is easy to measure and is a good indicator of decay. Lower strength means the fabric has decayed. For one part of the study, the researcher buried 10 strips of polyester fabric in well- drained soil in the summer. The strips were randomly assigned to two groups: 5 of them were buried for 2 weeks and the other 5 were buried for 16 weeks. Here are the breaking strengths in pounds: 126 126 Group 1 (2 wecks): Group 2 (16 weeks): 118 124 120 140 129 110 98 110 Do the data give convincing evidence at the x = .05 level that polyester decays more in 16 weeks than in 2 weeks? Test an appropriate hypothesis and state your conclusion in context. (Use the statology. org calculator: https://www. statology. org/two-sample-t-test-calculator/) Letji = mean breaking strength of the polyester after 2 weeks. 2 = mean breaking strength of the polyester after 16 weeks.
