Kudzu is a plant that was imported to the United States from Japan and now covers over seven million acres in the South. The plant contains chemicals called isoflavones that have been shown to have beneficial effects on bones. One study used three groups of rats to compare a control group with rats that were fed either a low dose or a high dose of isoflavones from kudzu. One of the outcomes examined was the bone mineral density in the femur (in grams per square centimeter). Researchers would like to test if the mean bone mineral density is different for the three different groups.
Using the data set BoneMineralData, conduct an ANOVA test to determine if there is a difference in the means of the 3 groups. Use a level of significance of alpha = 0.05 . Use this information to answer questions 1 through 5.Check that the requirements for this data are met. Check that data are normally distributed in each group and that the variances are equal for each group. Which of the following statements is true?a. The data are approximately normal for each group, the variances are equal for each groupb. The data are clearly not normal for each group, the variances are equal for each groupc. The data are approximately normal for each group, the variances are not equal for each groupd. The data are clearly not normal for each group, the variances are not equal for each group.
