Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Assign a variable 'female_avg' as the average female height.
female_avg <- 64
# Assign a variable 'female_sd' as the standard deviation for female heights.
female_sd <- 3
# To a variable named 'taller', assign the value of a height that is one SD taller than average.
# To a variable named 'shorter', assign the value of a height that is one SD shorter than average.
# Calculate the probability that a randomly selected female is between the desired height range. Print this value to the console.
