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:
<u>If you put a red blood cell in distilled water (100% H2O), there will be a net movement of water </u><u>from a region of higher concentration (100%) to a region of lower concentration </u><u>(the cell with 99.15% H2O). The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic (it contains less salt than the red blood cell) to the red blood cell. The red blood cell will gain water, swell ad then burst. The bursting of the red blood cell is called hemolysis.</u>
