Solution:
1. Given:
- Diagonal length of the square: d = 12

2. Use the relationship between the side length s of the square and the diagonal d:
- For a square, the diagonal is the hypotenuse of a right triangle formed by two sides of the square. Hence, using the Pythagorean theorem, we have:
s^2 + s^2 = d^2
- Simplify:
2s^2 = d^2

3. Solve for s:
- Substitute d = 12:
2s^2 = 12^2
2s^2 = 144

4. Divide both sides by 2:
s^2 = 72

5. Take the square root of both sides:
s = \sqrt{72}
s = \sqrt{36 \times 2} = 6\sqrt{2}

The length of one side of the square is 6\sqrt{2} units.

QUESTION l. An investigation has been carried out in a region to know the perception of "citizen insecurity" of its inhabitants. 1,270 people in the region were interviewed, of which 27.1% responded that it was a "serious" problem. Knowing that this opinion was previously held by 25.3% of the population of that region, we want to know if said opinion has changed significantly for a confidence level of 97.2%. Taking this statement into account, the following is requested: a) Critical value of the contrast statistic. b) Solve the hypothesis test and indicate what conclusion we can reach. c) P-value of contrast.
