<u>SAS Criterion:</u> If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
From the diagram you can see that:
<A ≅ <F ≅ <P
AB ≅ GF ≅ PQ
AC ≅ FE ≅ PR
This means that ΔABC, ΔFGE, and ΔPQR are congruent.
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
