In determining safe speed of a vessel we must consider visibility, traffic density etc.
<h3>What is safe speed?</h3>
The safe speed of a vessel is the maximum speed the vessel can be operated to avoid hazards such as collision, damage of vessel, etc.
<h3>Factors considered when determining safe speed of vessels</h3>
In determining safe speed of a vessel we must consider the following factors such as;
- Weather condition, eg visibility
- Traffic density,
- Background light at night, etc
Thus, in determining safe speed of a vessel we must consider visibility, traffic density etc.

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
