#Haemoglobin levels in athletes
Haeomoglobin concentration in the blood is a measure of how efficiently athletes can deliver oxygen to muscles during exercise. The aim of the study below was to generate reference values of haemoglobin concentration for athletes of different body sizes, against which blood samples from future athletes could be compared to inform their training programmes. The study measured haemoglobin concentration from 113 randomly selected Australian athletes, all of whom were performing at national level in their respective sports, and various body-size measurements for predictor variables.
Each row in athletes.csv corresponds to an athlete. The variables are
• Hconc: Haemoglobin concentration in blood (grams per decalitre).
• Sex: Sex, either M for male or F for female.
• Height: Height (cm).
• Weight: Weight (kg).
• LBM: Body mass other than fat (kg).
Conduct a full analysis, and include Methods and Assumption Checks along with an Executive Summary. In particular, we are interested in addressing a few questions of interest in the Executive Summary:
• What are the predicted haemoglobin concentration levels for a male and a female athlete, both with height 170 cm, weight 70kg, and lean body mass 60 kg?
• Is the relationship between haemoglobin concentration and height different for males than it is for females?
