In Questions 5 & 6 I have reproduced the exact code as the solution says, but I get different values. I have checked the seed is the same.

For Q5, you are right, it gives 25.6 For Q6, try this code, it returns the same value as the given answer col = gen(pcg(seed=365)) col_1 = col.normal(loc=3, scale=2, size=500) col_2 = col.exponential(scale=5, size=500) col_3 = col.logistic(loc=10, scale=4, size=500) print(np.max(np.array([col_1, col_2, col_3])))
