An experiment was carried out to investigate the effect of species (factor a, with i = 4) and grade (factor b, with j = 3) on breaking strength of wood specimens. one observation was made for each species—grade combination—resulting in ssa = 449.0, ssb = 425.6, and sse = 127.4. assume that an additive model is appropriate. test h0: α1 = α2 = α3 = α4 = 0 (no differences in true average strength due to species) versus ha: at least one αi ≠ 0 using a level 0.05 test. calculate the test statistic. (round your answer to two decimal places.)

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

(53.5 - 18.4) m.

step-by-step explanation:

after undergoing a displacement of 18.4m, the initial position was (53.5 - 18.4) m if an object has a final position of 53.5.
