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 speciesāgrade combinationāresulting in ssa = 449.0, ssb = 425.6, and sse = 127.4. assume that an additive model is appropriate. (a) test h0: Ī±1 = Ī±2 = Ī±3 = Ī±4 = 0 (no differences in true average strength due to species) versus ha: at least one Ī±i ā 0 using a level 0.05 test. calculate the test statistic. (round your answer to two decimal places.) f =

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
