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

Answer:
30
We'll be using the 5 numbers in your question.
In order to solve this problem, we need to know what range is.
The range is the spread of your data from the <u>lowest</u> to the <u>highest</u> value.
In order to find the range, we need to order the values from least to greatest.
Note: No picture of the stem-and-leaf plot is given in the question.
From least to greatest:
2, 5, 14, 19, 32.
Next, find the maximum and the minimum values.
Minimum: 2
Maximum: 32
Lastly, subtract the maximum and the minimum:
32-2=30.
Your range is 30.
The method which increased the spread of religion and new ideas between China and Japan in the 500s BCE is:
<u />
The method through which religion spread greatly between the countries of Japan and China in 500 BCE was through trade in the Silk Road.
As a result of this, there was trade between the merchants as they exchanged one piece of item for another and trade flourished.
This was a good opportunity to spread religion as the religions such as Buddhism, Islam and many others became very popular among the merchants.
Therefore, the correct answer is option C
