1. [1.66/6.66 Points] PREVIOUS ANSWERS DEVORESTAT9 10.1 .002.5. An article describes an experiment in which several types of boxes were compared with respect to compression strength (lb). The table below presents the results of a singlefactor ANOVA experiment involving I = 4 types of boxes. Type of Box Compression strength (lb) Sample Mean sample SD 1 655.5 788.3 734.3 721.4 679.1 699.4 713.00 46.55 2 789.2 772.5 786.9 686.1 732.1 774.8 756.93 40.34 3 737.1 639.0 696.3 671.7 717.2 727.1 698.07 37.20 4 535.1 628.7 542.4 559.0 586.9 520.0 562.02 39.87 IA uses Suppose that the compression strength observations on the fourth type of box had been 658.1, 751.7, 665.4, 682.0, 709.9, and 6430 (obtained by adding 123 to each previous x41). Assuming no change in the remaining observations, carry out an Ftest with a = 0.05. State the appropriate hypotheses.
