The technique that is known to be illustrated is said to be DNA hybridization.
<h3>What is DNA hybridization?</h3>In the study of genome, DNA hybridization is known to be a kind of a molecular biology method that is often used to know the measures or the degree of genetic similarity that exist between a given pools of DNA sequences.
DNA hybridization is also seen as ability of two given strand of complementary DNA that tends to pair with another strand and it is one that can be used to find out other similar DNA sequences in two other kinds of species or within a given genome of a single species.
Note that in the case above, The technique that is known to be illustrated is said to be DNA hybridization.

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
