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.

Construct one table that includes relative frequencies based on
the frequency distributions shown below, then compare the amounts
of tar in nonfiltered and filtered cigarettes. Do the cigarette
filters appear to be effective? (Hint: The filters reduce the
amount of tar ingested by the smoker.)

Consider the following IQ data obtained from a sample of 25
incarcerated youth. Convert the 25 raw adjustment scores to
standardized scores. Show work for at least one of the 25 scores.
(Hint: You need to calculate the mean and SD first!) (4pts
for entire column) *For this question, only TWO decimal
places are required.
