This is a highly interactive class with live Q&As and interactions with Dr. Choi each week.

Quantify the dependence between the variables (LVM and BMI) by calculating the coefficient of determination. Use that information to choose one statement below.

Generate a plot of the residuals. Include the reference line at y=0 (1 point for residuals, 1 point for reference line, 1 point for axis properly labeled and a title)

OPTIONAL QUESTION – Upload any additional notes

To answer this question your code must show what test you use to decide if the argument is true or false.    Based on the analysis we fail to reject the null hypothesis.

We will first focus on LVM data in female participants with normal blood pressure and those that are hypertensive.  What is the mean LVM in individuals with normal blood pressure [LVM_norm] and the mean LVM in hypertensive individuals [LVM_hyp]?  What is the standard deviation of the LVM in individuals with normal blood pressure [std_norm] and the standard deviation of the LVM in hypertensive patients [std_hyper]? Report your answer using 3 significant figures. 

Many children have ear tubes surgically inserted to reduce hearing loss associated with persistent ear infection (otorrhea). A common side effect with ear tubes is discharge from the external ear indicating inflammation of the external or middle ear. A clinical trial was conducted among children with prior ear infections comparing efficacy of (i) antibiotic eardrops and (ii) oral antibiotics. Children were seen at home by study physicians at 2 weeks. The results are given in the Table below.  Observed data: Group Otorrhea 2 weeks = yes Otorrhea 2 weeks = no Total Antibiotic Ear Drops 4 72 76 Oral Antibiotic 34 43 77 Total 38 115 153

Calculate the standard error of the LVM in females with normal blood pressure and in the hypertensive group. Which group had the smallest standard error?
