Instructions: Address the following problem and obtain and write down the F-score and p- value in five decimal places. Imagine you manufacture paper bags and you want to improve the tensile strength of the bag. You suspect that changing the concentration of hardwood in the bag will change the tensile strength. You measure the tensile strength in pounds per square inch (PSI). Šo, you decide to test this at 5%, 10%, 15% and 20% hardwood concentration levels. Imagine that you've conducted random trials at each of the four levels of hardwood concentration. The data obtained are presented in the table. Test at 0.05 level of significance whether there are significant differences among the treatments. Hardwood concentration % 5% 10% 15% 20% Obs1 7. 12 14 19 Obs2 8 17 18 25 Obs3 15 13 19 22 Obs4 11 18 17 23 Obs5 19 16 18 Obsó 10 15 18 20
