Cоnsider а study оf Mаth scоres (Mаth) for n=14 students with information about their undergraduate major (Major) and weekly hours of study (Hours). The goal was to fit a regression model to express the dependence of Y (Math) on X (Hours) and Major (Engineering, History, or Science). Type your answers to the following questions in the text box below making sure to reference the relevant Minitab output in your answers. (5 pts) Clearly define a set of indicator variables that could be used in a regression model to represent the qualitative variable Major. [Hint: Think carefully about the number of indicator variables needed given the number of levels of Major and use "Engineering" as the reference level.] (5 pts) Write a population multiple linear regression equation for predicting the Math scores in terms of Hours and Major. Since Major could impact the dependence of Math score (Y) on Hours (X), include in the model interaction effects between Hours and Major, together with their main effects. [Hint: Your equation should include Y, X, the indicator variables you defined in part (a), interaction terms, and population regression coefficients (β’s). Do not include estimated coefficients, i.e., numbers, in this part.] (8 pts) Conduct a single hypothesis test based on the model from part (b) to determine whether the average change in Math score per one additional Hour of study per week differs by Major. Write the null and alternative hypotheses, the test statistic, the p-value, and the conclusion based on a significance level of 0.05. Use relevant parts of the following Minitab output to support your answer. [Not all the output is relevant.] (8 pts) Write a new population regression model based on your conclusion to part (c). Then conduct two separate hypothesis tests based on this new model for whether the mean Math score for a fixed number of Hours of study per week differs by Major. For each test, write the null and alternative hypotheses, the test statistic, the p-value, and the conclusion based on a significance level of 0.05. Use relevant parts of the following Minitab output to support your answer. [Not all the output is relevant.] (6 pts) Based on your conclusion to part (d), write three fitted regression equations that can be used to predict the Math score from the Hours of study per week for each Major. [Hint: Your equations should include number values, not β’s.] (4 pts) Based on one of the equations from part (e), predict the Math score for a History major who studies 4 hours a week. A point estimate is sufficient.
This is а big questiоn, sо pleаse аnswer all оf it. Please label your answers (A-L) to match each of the questions. Immune responses can be specialized to respond to three different categories of infectious threat (pathogen). One of these categories is the intracellular pathogen category. a. Give an example of an effector cell that would be an expected responder to this type of pathogen. (Maybe read the other parts of this question before answering).b. What is the mechanism by which this cell mediates its effector function?c. Is this cell part of the innate or adaptive immune system?d. Is this cell considered to be a sentinel cell?e. What lineage of bone marrow stem cell does this cell derive from?f. Does this cell need to travel to the site of pathogen infection, or can this cell do its effector function from a distance?g. Could this cell be considered part of either the humoral or cellular arms of the immune sytem? If so, which one?h. As part of its effector function, does this cell target the pathogen directly or indirectly?i. Can this cell present antigen?j. Can this cell provide defense against other categories of pathogen? If so, what category?k. Does this cell need to undergo tolerance processes?l. Can this cell recognize antigen? Question 1: Your Answer: A. For intracellular pathogens, either cytotoxic T-cells or B. The mechanism by which this cell mediates it's effector function is by binding to the MHC Class 1 receptor on the membrane of an antigen presenting cell. APCs can be any immune cell. C. This cell is a part of the adaptive immune system. D. This cell is not a sentinel cell, the sentinel cells are dendritic cells, macrophages, and mast cells.
