s a first step in developing a new drug to treat cancer in humans, an initial study of the drug is undertaken in rats. Three hundred rats with cancer are studied, and each is assigned to one of three treatments. One hundred rats are randomly assigned to a high dose of the new drug, 100 are randomly assigned to a low dose, and 100 are randomly assigned to a control group (no drug). After six months, each rat is examined and classified as having developed no tumors, one tumor, or two or more tumors.

Which of the following would be an appropriate alternative hypothesis in this study for a chi-square test for homogeneity of tumor response across treatments?

Answers

Answer 1


The appropriate alternative hypothesis for a chi-square test for homogeneity of tumor response across treatments would be:

- There is a significant association between the treatment received and the number of tumors developed by rats.

In other words, the null hypothesis would be that there is no association between the treatment received and the number of tumors developed by rats. The alternative hypothesis would state that there is a significant association between these variables. This hypothesis can be tested using a chi-square test, which would compare the observed frequencies of tumor response in each treatment group to the expected frequencies if there were no association between treatment and tumor response.

Explain whether the research topic is best investigated through an experiment or an observational study. Then describe the design of the experiment or observational study.1. A researcher wants to test whether stretching after exercising decreases the number of injuries due to muscle damage. Identify a potential problem, if any, with each experimental design. Then describe how you can improve it.a) The researcher selects 400 people who exercise on a regular basis. The people are divided into two groups based on age. Within each age group, the people are randomly assigned to stretch after exercising or to not stretch. The people's occurrence of injuries due to muscle damage is monitored. The stretching after exercise significantly decreases the number of injuries due to muscle damage.b) The researcher randomly selects 150 people who exercise on a regular basis.Half the people stretch after exercising, and the number of their injuries due to muscle damage is monitored. The other half do not stretch after exercising, and the number of their injuries due to muscle damage is monitored. The number of injuries due to muscle damage significantly decreases for those who stretch after exercising. when the level of debt increases the risk to debt holders, does it also increase the rsik to equity holders? if it does, what happens to the required return to equity as more debt is used? which of the point mutations is unlikely to change a protein's ability to function? select all that apply. 1.
