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

According to the context, the correct sentence with the irregular verb in the imperfect tense is <em>¿</em><em>veías</em><em> a tu padrastro todos los días?.</em>
<h3>What is the imperfect tense?</h3>
It refers to actions with a certain duration in the past or that were carried out simultaneously with other actions.
As with other verb tenses, there are rules for conjugating verbs in the imperfect tense in Spanish, where the ending of the verb will change depending on the subject of the sentence and the original ending in the infinitive.
However, the verb ''ver'' has an irregular verb conjugation and is pronominal, so it will not follow the regular verb conjugation rules.
Therefore, we can conclude that according to the context, the correct sentence with the irregular verb in the imperfect tense is <em>¿</em><em>veías</em><em> a tu padrastro todos los días?.</em>

Both of them.
An analog signal is one that is continuous in both instances of time and amplitude.
Now, in the real world examples of Analog signals are; current, voltage, temperature, pressure, light intensity etc.
Meanwhile, the digital signals are those that contain the digital values which are usually converted at specific instances from the analog signal.
This means that they can have only 2 states which is On or Off.
