Answers
3x + 5 = 5x - 13
Subtract
3x
from both sides:
5 = 2x - 13
Add 13 to both sides:
18 = 2x
Divide both sides by 2:
x = 9
Answer:
x = 9

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.
