Hypothesis Testing

We can perform a t-test to compare the means of weight between two age groups.

Step 1: Create Age Groups

rCopy code# Create a new variable to classify age groups
data$age_group <- ifelse(data$age > 30, "Above 30", "30 or Below")

Step 2: Conduct a t-test

rCopy code# Perform a t-test to compare weights between the two age groups
t_test_result <- t.test(weight ~ age_group, data = data)

# Display the results
print(t_test_result)
