Transcribed Image Text:
A researcher studying genetic influences on learning compares the maze performance of four genetically different strains of mice, using eight mice per strain, with the accompanying performance results. Using the 0.01 significance level, is there an overall difference in maze performance among the four strains? Complete parts (a) through) below. Click the icon to view the performance results. Click here to view Page 1 of the outoff F score table. Click here to view Page 2 of the cutoff Escore table. Click here to view Page 3 of the cutoff F score table. Click here to view Page 4 of the cutoff F score table. (a) Use the steps of hypothesis testing. Determine the null and research hypotheses. Choose the correct answer below OA. The null hypothesis is that at least two of these populations have the same mean. The research hypothesis is that the population means are not the same. OB. The null hypothesis is that the population means are not the same. The research hypothesis is that these populations have the same mean (₂₂). OC. The null hypothesis is that the population means are not the same. The research hypothesis is that at least two of these populations have the same mean. OD. The null hypothesis is that these populations have the same mean (₁₂"). The research hypothesis is that the population means are not the same. Determine the characteristics of the comparison distribution. The comparison distribution will be an F distribution with dfastween F and dfas Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected.
