A patient arrives in the ED with symptoms of acute myocardial infarction (AMI). What are the initial priorities for collaborative care of the patient? Select all that apply. 

11. Data were collected from a random sample of 220 home sales from a community in 2013. Let Price denote the selling price (in $1000), BDR denote the number of bedrooms, Bath denote the number of bathrooms, Hsize denote the size of the house (in square feet), Lsize denote the lot size (in square feet), Age denote the age of the house (in years), and Poor denote a binary variable that is equal to 1 if the condition of the house is reported as “poor”. An estimated regression yields [6 points] Is the coefficient on BDR statistically significantly different from 0? [10 points] A homeowner purchases 2000 square feet from an adjacent lot. Construct a 95% confidence interval for the change in the value of her house. [8 points] Compare the prices of two houses, one for the house constructed 20 years earlier (Age of the house is 20 units higher).  [6 points] The F-statistic for omitting BDR, Age and Hsize from the regression is F = 3.2. Are the coefficients on BDR, Age and Hsize statistically different from 0 at the 5% level? [12 points] Are the individual coefficients for Bath, Hsize, Lsize and Poor statistically significant? Please use the 1% significance level and a two-sided test.   

What is the recommended therapeutic range for the International Normalized Ratio (INR) for a patient with a history of venous thromboembolism receiving warfarin therapy?

5. Imagine that you were told that the t-statistic for the slope coefficient of the regression line  was 4.38. What are the units of measurement for the t-statistic?

The nurse is caring for several postoperative patients at risk of developing pulmonary embolism. Which intervention is best for the prevention of the development of VTE and pulmonary embolism? 

4. If the errors are heteroskedastic, then

The process of  _____  result(s) in chromosomes that have alleles from both the mother and the father.

5. Imagine that you were told that the t-statistic for the slope coefficient of the regression line  was 4.38. What are the units of measurement for the t-statistic?

1. The interpretation of the slope coefficient in the model is as follows:

In 1883, Theodor W. Engelmann conducted a classic experiment in which he illuminated a filament of photosynthetic algae with light that passed through a prism, thus exposing different segments of the algae to different wavelengths of light. He then added aerobic, nonphotosynthetic bacteria, and noted that the largest groups of bacteria were found in the areas illuminated by the red and blue light. Using what you know about photosynthesis and cellular respiration, which of the following would best explain the reason for the bacteria congregating in the regions with red and blue light?
