What is the appropriate statistical test to assess whether there is an association between obesity status (normal weight, overweight, obese) and 5-year incident cardiovascular disease (CVd.? Suppose each participant’s obesity status (category) is known along with whether they develop CVD over the next 5 years or not.

Answer #1

The most appropriate test will be the Log-Rank test to assess whether there is an association between obesity status (normal weight, overweight, obese) and 5-year incident cardiovascular disease (CVD). Since this problem is a time to event analysis, the log-rank test is suitable here, which is a non-parametric test used to compare the survival distributions of two samples.

Suppose we want to design a new study to assess the implications of childhood obesity on poor health outcomes in adulthood. In the study we will consider total cholesterol at age 50 and incident cardiovascular disease by age 50 as the key outcomes. We will compare normal versus overweight/obese children. Assume that the standard deviation in total cholesterol is 35. a. How many normal and overweight/obese children are required to ensure that a 95% confidence interval estimate for the difference...

Researchers at a cardiovascular institute are concerned about the association between exercise and hypertension among their patient population. Suppose in order to assess this relationship, the researchers conducted a cohort study where a population of 35-55 year old participants were enrolled and followed for a period of 10 years, and required to submit weekly diary submissions about their exercise routines. The researchers then conducted clinic visits where blood pressure was measured and hypertensive status was confirmed. Suppose the following table...

Problem Set 2: Pearson’s correlation (7 pts) Research Scenario: Is there a positive relationship between grit and GPA in high school seniors? A researcher examined this issue by having students beginning their senior year of high school complete a grit inventory using a Likert-based scale (range 1 – 7), where higher numbers indicate more “grit”. GPA was self-reported (scale 0 – 4.0). Enter the data shown here into SPSS to assess whether there is a positive relationship between grit and...

A researcher is concerned that his new antihypertensive medication may be causing insomnia in some of his patients. Suppose he gathers a SRS of 65 patients treated with the study drug with a sample average of 6.6 hours of sleep and a σ=1.1. Assuming that insomnia can be quantified as an average of 4.5 hours of sleep, can we determine with 95% confidence that his drug avoids diagnosis of insomnia as a side-effect?                Ho: µ=4.5, Ha: µ<4.5 Z stat=12.4...
