researchers from the institute for behavioral genetics at the university of colorado investigated the effect that the enzyme protein kinase C has on anxiety in mice.the genotype for a particular gene in a mouse consists of two alleles of each chromosome, one each from the father and mother.the investigators in the study separated the mice into three groups.in group 0,neither of the mice's alleles for PKC produced the enzyme.in group 1,one of the two alleles for PKC produced the enzyme and the other did not.in group 2,both PKC alleles produced the enzyme.to measure the anxiety in the mice. scientists measures the time the mice spent in the "open-ended"sections of an elevated maze.it was surmised that mice soending more time in open-ended sections decreased anxirty.the data are prvided in table.use technology to test at 0.01 whether the population mean time spent in the open-ended sections of the maze was the same for all three groups
