Fit a model to predict bill length from bill depth with different intercepts (but not slopes) based on sex for the palmerpenguins data.

a) What is the estimated intercept term for female penguins?

a) est_intercept_female = 16.382
b) est_intercept_male = 21.958
c) exp_bill_length_male_14mm = 43.340
d) pred_interval_female_19mm = (43.430, 48.957)
e) confidence_interval_slope = (0.192, 0.461)
f) q2.f = TRUE
