Question Assignment description
#14Kudzu is a plant that was imported to the US from Japan and now covers over seven million acres within the South. The plant comprises chemical substances known as isoflavones which were proven to have useful results on bones. One examine used three teams of rats to examine a management group with rats that had been fed both a low dose or a excessive dose of isoflavones from kudzu. One of many outcomes examined was the bone mineral density within the femur (in grams per sq. centimeter). Listed here are the information.TreatmentBone mineral density (g/cm2) Management zero.228 zero.207 zero.234 zero.220 zero.217 zero.228 zero.209 zero.221 zero.204 zero.220 zero.203 zero.219 zero.218 zero.245 zero.210 Low dose zero.211 zero.220 zero.211 zero.233 zero.219 zero.233 zero.226 zero.228 zero.216 zero.225 zero.200 zero.208 zero.198 zero.208 zero.203 Excessive dose zero.250 zero.237 zero.217 zero.206 zero.247 zero.228 zero.245 zero.232 zero.267 zero.261 zero.221 zero.219 zero.232 zero.209 zero.255 On this examine there have been three teams. Controls obtained a placebo, and the opposite two teams obtained both a low or a excessive dose of isoflavones from kudzu. You might be planning the same examine of a brand new form of isoflavone. Use the outcomes of the examine above to plan your examine. Write a proposal explaining why your examine must be funded.#15 The Nationwide Crime Victimization Survey estimates that there have been over 400,000 violent crimes dedicated towards girls by their intimate companion that resulted in bodily damage. An intervention examine designed to enhance security behaviors of abused girls in contrast the effectiveness of six phone intervention classes with a management group of abused girls who obtained commonplace care. Fifteen completely different security behaviors had been examined. One of many variables analyzed was the whole variety of behaviors (out of 15) that every lady carried out. Here’s a abstract of the technique of this variable at baseline (simply earlier than the primary phone name) and at follow-up three and 6 months later.Time Group Baseline three months 6 months Intervention10.four 12.5 11.9 Management 9.6 9.9 10.four (a) Discover the marginal means. Are they helpful for understanding the outcomes of this examine?This reply has not been graded but.(b) Plot the means. Do you suppose there’s an interplay? Describe the which means of an interplay for this examine.#16The quantity of chromium within the weight loss plan has an impact on the way in which the physique processes insulin. In an experiment designed to examine this phenomenon, 4 diets had been fed to male rats. There have been two elements. Chromium had two ranges: low (L) and regular (N). The rats had been allowed to eat as a lot as they wished (M) or the whole quantity that they may eat was restricted (R). We name the second issue Eat. One of many variables measured was the quantity of an enzyme known as GITH. The means for this response variable seem within the following desk.EatChromiumMRL4.5455.175N4.4255.317(a) Make a plot of the imply GITH for these diets, with the issue Chromium on the x axis and GITH on the y axis. For every Eat group join the factors for the 2 Chromium means. This reply has not been graded but.(b) Describe the patterns you see. Does the quantity of chromium within the weight loss plan seem to have an effect on the GITH imply? Does proscribing the weight loss plan fairly than letting the rats eat as a lot as they need seem to have an impact? Is there an interplay?This reply has not been graded but.(c) Compute the marginal means. Compute the variations between the M and R diets for every stage of Chromium. Use this data to summarize numerically the patterns within the plot.
