Answer:
In South Carolina, the CCC created 16 state parks that maintain some of the state's most stunning places. This work provided access to thousands of acres of general land to all South Carolinians. It even gave employment to the unemployed and helped many households endure difficult times.
The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
<u>Canadians</u>
- Sample size = 50
- Mean = 4.6
- Standard deviation = 2.9
<u>Americans</u>
- Sample size = 60
- Mean = 5.2
- Standard deviation = 1.3
The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:
The standard error of the Canadian sample is:
So, we have:
The standard error of the American sample is:
So, we have:
The standard error of the difference of sample means is then calculated as:
This gives
Take square roots
Hence, the standard error of the difference of sample means is 0.444

The Earth is known as a spherical body. The force of gravity of the Sun on Earth in June compared to December is slightly smaller.
- Earth is simply known to slightly closer to the Sun on one side of its orbit than on the other side.
Kepler's second law states that as a planet moves round the Sun, it sweeps out equal areas in equal times.
All the planets do moves around the Sun in nearly the same plane. The Sun is found to be slightly off-center from the middle of each planet's orbit.
