1) What is the value of b1? X: 12, 21, 28, 8, 20. Y: 17, 15, 22,
19, 24
2) What is the value of b0? X: 12, 21, 28, 8, 20. Y: 17, 15, 22,

3) What is the equation of the y-hat estimator line? X: 12, 21,
28, 8, 20. Y: 17, 15, 22, 19, 24.
a. Y=0.162-16.51x b. y=0.162+16.51x c. Y=16.51-0.162x d.
Y=16.51+0.162x
4) If x is increased by 10 units, how much does y-hat...
Consider the magic matrix:
A = np.array([[17, 24, 1, 8, 15],

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.
