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
# Using variables 'female_avg' and 'female_sd', calculate the probability that a randomly selected female is shorter than 5 feet. Print this value to the console.
