This is a bio-statistic class. please help with this questions. Thanks.

Multiple Choice 1. A subset of the population of interest is often referred to by what statistical term? A) A sample of individuals B) A subculture of individuals C) A class of individuals D) A minority group 2. The measure of uncertainty in a biostatistician's calculation of a particular outcome that may result from using a subset of the population to estimate the actual likelihood of the event occurring in the population as a whole is referred to by what statistical term? A) A chance error B) A systematic error C) A standard error D) A margin of error 3. Which of the following most appropriately describes how the data from a cross-sectional study can be applied to a population? A) The data generated from a cross-sectional study can be applied to new or changing populations regardless of the amount of time that has passed since the study was conducted. B) The data generated from a cross-sectional study is only applicable to the original population of interest during the time that the study was conducted. C) The data generated from a cross-sectional study is applicable to any group of individuals with similar characteristics to the original population of interest. D) The data generated from a cross-sectional study is applicable to all individuals regardless of how much those individuals differ from the original population of interest. 4. Researchers have conducted a study and determined that the relative risk for developing a cold for individuals taking vitamin C is 0.47 when compared to the number of participants in the study who developed a cold while not taking vitamin C. This is an indication of which of the following? A) This indicates that people who took vitamin C were 47% more likely to catch a cold and that taking vitamin C makes people more susceptible to catching a cold. B) This indicates that the individuals taking vitamin C were 47% less likely to catch a cold and that taking vitamin C has a protective effect, making them less likely to catch a cold. C) This indicates that the individuals taking vitamin C were 53% less likely to catch a cold and that taking vitamin C has a protective effect, making them less likely to catch a cold. D) Only relative risk ratios above one are statistically significant, a relative risk ratio below one indicates there is no difference between the individuals who take vitamin C and those individuals who do not. be applied to? 5. Which is the most important factor in determining which populations a well-designed study's results can A) The inclusion and exclusion criteria for the study B) The randomization of participants for a study C) The type of study being conducted D) The presence of blinding throughout the study True/False 1. True or False? Biostatistics is defined as the application of statistical principles in medicine, public health, or biology. 2. True or False? The data collected in a biostatistics study can be applied to any population regardless of race, class, and socioeconomic status. 3. True or False? A relative risk of 5.67 indicates that the group of individuals in a study exposed to the particular variable of interest are 5.67 times more likely to experience the observed outcome being studied. 4. True or False? Oftentimes it is more difficult to establish a relationship between a particular disease outcome and a risk factor among older adults because they also have other risk factors for disease. 5. True or False? Randomization of clinical trial participants is important to ensure that clinical trial participants in the treatment group and comparator group allow the study's results to be generalized to the population as a whole, and not just the subgroup of individuals that participated in the study because of the balance promoted through the randomization process
