# Reading in data
athletes <- read.csv(file='https://raw.githubusercontent.com/artofstat/data/master/Chapter13/college_female_athletes.csv')
colnames(athletes) #check column names

# Fitting in multiple regression models
linReg <- lm(TBW ~ HGT + BF + AGE, data = athletes)

# To view the F-statistic, you can use the summary of the regression model
# You will find the overall F-statistic at the last line of the summary
