In your problem, the aqueduct rises 3 meters (Rise= 3) for every kilometer (1,000 meters) in length (Run = 1,000), so the slope is Rise/Run=3/1000=0.003.

Answer:
c. [70.30, 74.70]
Step-by-step explanation:
Confidence interval is a range of values in which there is a specified probability that the value of a parameter lies within that range.
The confidence interval of a statistical data can be written as.
x+/-zr/√n .......1
Given;
Mean gain x = 72.5 cm
Standard deviation r = 4.5 cm
Number of samples n = 16
Confidence interval = 95%
z (at 95% confidence) = 1.96 (from the table)
Substituting the values we have into equation 1;
72.5 +/- 1.96×4.5/√16
72.5 +/- 2.20 cm
[70.30, 74.70]
Therefore, the 95% confidence interval is
[70.30, 74.70] cm
