PUBH 8500 Walden Assumptions of Linearity Sampling independence Normality & Homoscedasticity Paper
Assignment: AssessmentThe testing of assumptions, recognition of limitations, and proper use of diagnostics are all necessary elements in the use of multiple linear regression for public health research. All of these elements allow biostatisticians to better assess the results of multiple linear regression models.For this Assignment, you test that assumptions for multiple linear regression have been met, use SPSS to create a multiple linear regression, evaluate results to determine whether the model is appropriate, and finally interpret the relationships uncovered through this statistical test between the independent and dependent variables. Use the Week 4 Dataset (SPSS document) from the Learning Resources area to complete this assignment.The AssignmentExplain the assumptions of Linearity, Sampling independence, Normality, and Homoscedasticity (or equal variance). (30 points)How would you test whether these have been met? (Note: for the exam you do not need to test these assumptions)Using SPSS, test the assumption of Linearity between the independent and dependent variables.Using SPSS, test the assumption of Normality for the dependent variable.Conduct a multiple linear regression using SPSS. Provide relevant SPSS output and assess the statistical significance of the effects of mother’s Age, BMI, and Coffee (Cups per Day) on Birth weight. (30 points)Explain the practical implications of your finding. Include a reference to the R square of the model in your discussion. (20 points)Discuss whether or not there is interaction (effect modification) first between Age and BMI and second between BMI and Coffee. (20 points)

If f '(x) exists and is nonzero for all x, then f(1) ≠ f(0). II. If f is differentiable for all x and f (-1) = f(1), then there is a number c, such that |c| < 1 and f '(c) = 0. III. If f '(c) = 0, then f has a local maximum or minimum at x = c.I onlyII onlyI and III onlyI and II only10.The local linear approximation of a function f will always be less than or equal to the function's value if, for all x in an interval containing the point of tangency, (5 points)f ' < 0f ' > 0f " < 0f " > 01.Find the x-coordinates of any relative extrema and inflection point(s) for the function f(x) = 6x(1/3) + 3x(4/3). You must justify your answer using an analysis of f '(x) and f "(x).2.What is the maximum volume in cubic inches of an open box to be made from a 16-inch by 30-inch piece of cardboard by cutting out squares of equal sides from the four corners and bending up the sides? Your work must include a statement of the function and its derivative. Give one decimal place in your final answer.3.The position function of a particle in rectilinear motion is given by s(t) = t3 - 12t2 + 45t + 4 for t ≥ 0 with t measured in seconds and s(t) measured in feet.
