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.)

Thompson and thompson is a steel bolts manufacturing company. their current steel bolts have a mean diameter of 127 millimeters, and a variance of 36. if a random sample of 35 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by greater than 0.5 millimeters? round your answer to four decimal places.
