The statement "A chi-squared goodness-of-fit can be used to test hypotheses about the proportion of the population falling into each of the possible categories" is true because it is commonly used to determine whether observed categorical data follows an expected distribution or proportion across different categories. Meanwhile, the statement "the observed cell counts are compared to the cell counts that would be expected when the alternative hypothesis is true" is false because the observed cell counts are compared to the expected cell counts under the null hypothesis
A chi-squared goodness-of-fit can be used to test hypotheses about the proportion of the population falling into each of the possible categories.
This statement is true. A chi-squared goodness-of-fit test is commonly used to determine whether observed categorical data follows an expected distribution or proportion across different categories. It is used to test whether the observed frequencies in each category are significantly different from the expected frequencies based on a specified null hypothesis.
In order to decide whether the observed data is compatible with the null hypothesis, the observed cell counts are compared to the cell counts that would be expected when the alternative hypothesis is true.
This statement is false. In a chi-squared goodness-of-fit test, the observed cell counts are compared to the expected cell counts under the null hypothesis, not the alternative hypothesis. The purpose is to assess whether there is evidence to reject the null hypothesis and conclude that the observed data significantly deviates from the expected distribution.
Therefore, the correct statements are:
A chi-squared goodness-of-fit can be used to test hypotheses about the proportion of the population falling into each of the possible categories. (True)
In order to decide whether the observed data is compatible with the null hypothesis, the observed cell counts are compared to the cell counts that would be expected when the alternative hypothesis is true. (False)

Imagine that you are working with a team of bioarchaeologists that has just excavated a medieval cemetery site in Italy. The cemetery has over 200 graves, with all sexes and ages represented in the skeletal sample. You are interested in knowing whether there were gender differences in health among members of the medieval community. How would you answer this question using the skeletal remains
Answer:
By analyzing the pelvis bone (sex determination) and the length of the diaphyseal bone and nonsynovial joints (age determination of non-adult skeletons and adult skeletons, respectively)
Explanation:
Bioarchaeologists are professionals that study human skeletons from archaeological sites. Bioarchaeologists can estimate the age and sex of human skeletons and thus determine the health and dynamics of past human populations. In regard to sex determination, the pelvis is a bone that can be used to estimate the sex of an individual with an accuracy higher than 95%. In regard to the age, characteristics associated with bone growth such as, for example, the length of the diaphyseal bone, can be good indicators to estimate the age of non-adult skeletons, while nonsynovial joints (i.e. joints without a synovial membrane) which are commonly called synarthroses or solid joints, can be used to estimate the age of adult skeletons.

The risk of getting lung cancer at some point in time in one's life for men who have never smoked is about 13 in 1000. The risk for men who smoke is just over 13 times the risk for non-smokers. What is the approximate lifetime risk of getting lung cancer for men who smoke
0.169 is the approximate lifetime risk of getting lung cancer for men who smoke.
In the United States, about 10 to 20% of lung cancer cases, or 20,000 to 40,000 lung cancers each year, occur in people who have never smoked or have smoked fewer than 100 cigarettes in their lifetime.
In this case, if we talk about the risk of smokers in terms of the risk of non-smokers, so the baseline risk is the risk for the non-smokers. So the baseline risk for lung cancer in men over an entire lifetime is the risk of lung cancer for men who have never smoked, over their lifetime, which is =0.013
The approximate lifetime risk of getting ling cancer, for male smokers, can be calculated as being 13 times the base risk= 0.169

Which best describes how lenalidomine and thalidomide function in the body?
Both drugs treat multiple myeloma by inhibiting inflammation, inhibiting formation of red blood cells, and modulating the immune system to kill cancer cells.
Both drugs treat leukemia by depriving the cancer cells of asparagine and preventing protein formation resulting in cellular death.
Both drugs treat breast cancer by blocking the aromatase enzyme necessary for estradiol production.
Both drugs treat lymphoma by aiding the immune system in identifying and binding to antigen proteins on the surface of cancer cells and triggering the cell to die.
Answer:
Multiple myeloma is a B-cell malignancy characterized by an excess of monotypic plasma cells in the bone marrow. The molecular mechanisms that are involved in disease progression depend on the interaction between the multiple myeloma cells and the bone microenvironment. Because these mechanisms have been well characterized, it is possible to develop regimens that are more specific to pathways involved in the pathogenesis of multiple myeloma than is typical for conventional chemotherapy in disease management. Thalidomide and immunomodulatory drugs (IMiDs) have now been shown to block several pathways important for disease progression in multiple myeloma. First established as agents with antiangiogenic properties, thalidomide and IMiDs inhibit the production of interleukin (IL)-6, which is a growth factor for the proliferation of myeloma cells. In addition, they activate apoptotic pathways through caspase 8-mediated cell death. At the mitochondrial level, they are responsible for c-jun terminal kinase (JNK)-dependent release of cytochrome-c and Smac into the cytosol of cells, where they regulate the activity of molecules that affect apoptosis. By activating T cells to produce IL-2, thalidomide and IMiDs alter natural killer (NK) cell numbers and function, thus augmenting the activity of NK-dependent cytotoxicity. Data delineating these events have been derived from experiments done in resistant and sensitive multiple myeloma cell lines. Although thalidomide and IMiDs demonstrate similar biologic activities, IMiDs are more potent than thalidomide and achieve responses at lower doses. Lenalidomide, a thalidomide derivative, has also been shown to have a different toxicity profile. Our understanding of the mechanism of action of these agents has provided a platform for exciting clinical trials evaluating combinations of thalidomide and lenalidomide with both conventional chemotherapy and newer targeted agents.
