Answer:
all three sampling distributions appear to follow the normal distribution
Step-by-step explanation:
Sampling distribtuions follow a normal distribution.
The distance of the yacht from the ship is 35 km
<h3>How to determine the distance?</h3>
See attachment for the diagram that represents the given parameters.
The distance of the yacht from the ship is then calculated using the following law of cosine.
YS^2 = ST^2 + YT^2 - 2 * ST * YT * cos(T)
This gives
YS^2 = 24^2 + 12^2 - 2 * 24 * 12 * cos(155)
Evaluate the exponents and the products
YS^2 = 576 + 144 + 522
Evaluate the sum
YS^2 = 1242
Take the square root of both sides
YS = 35
Hence, the distance of the yacht from the ship is 35 km
