Answer:
Option B.
Step-by-step explanation:
Given information:
We need to find 95% confidence interval estimate for the difference between the means of two normally distributed populations.
Formula for confidence interval:
From the standard normal table it is clear that the z value at 95% confidence interval is 1.96.
Substitute the given values in the above formula.
The lower confidence limit is −18.78.
Therefore, the correct option B.
(32°) = 1700 feet / x => x = 1700 feet / tan(32°) = 1700 feet / 0.625 = 2720 feet.
You cannot calculate this.
