of wine. A random sample of 130 people who drink at least one

Consider the magic matrix:
A = np.array([[17, 24, 1, 8, 15],
[23,
5, 7, 14, 16],
[
4, 6, 13, 20, 22],
[10,
12, 19, 21, 3],
[11,
18, 25, 2, 9]])
The matrix A has 5 row sums (one for each row), 5 column
sums (one for each column) and two diagonal sums. These 12 sums
should all be exactly the same. Verify that they are the same by
printing them and “seeing” that they are the same.
