Randomization Distribution for Heart Rate and Blood Pressure Use StatKey or other technology to create the randomization
Question:
Randomization Distribution for Heart Rate and Blood Pressure Use StatKey or other technology to create the randomization distribution for the data in Exercise B.50. Use the distribution to estimate the p-value for the test. Are the results statistically significant?
Randomization Samples In Exercises B.52 to B.56, a situation is described for a statistical test. In Section 4.1 you were asked to state the null and alternative hypotheses (Exercises 4.9 to 4.13). Here, for each situation, describe how you might physically create one randomization sample and compute one randomization statistic (without using any technology) from a given sample. Be explicit enough that a classmate could follow your instructions (even if it might take a very long time).
Heart Rates and Blood Pressure Table B.7 shows the heart rates and systolic blood pressure for eight 55-year-old patients from the Intensive Care Unit data introduced in Data 2.3 on page 66 and available at ICUAdmissions. We are testing to see if the data provide evidence of a positive correlation between these two variables for 55-year-old ICU patients.
Exercise B.50.
Data 2.3
The dataset ICUAdmissions24 includes information on 200 patients admitted to the Intensive Care Unit at a hospital. Twenty variables are given for the patients being admitted, including age, gender, race, heart rate, systolic blood pressure, whether or not CPR was administered, and whether or not the patient lived or died.
