Answer:
B. Words stored in echoic memory will last for 3 to 4 seconds, so you can still recall her words.
Explanation:
We have different types of memory, one of those types of memory is echoic memory.
This memory is a type of sensory memory that register sounds, when we first hear something, the sound is stored in this memory so it can be processed. The stimuli last about 3 to 4 seconds in the echoic memory (that's why sometimes we can hear something after it was said even if we're not paying attention)
In this example, your mom is lecturing you and you lose concentration, when she asks you if you're listening and you are able to repeat the last few things she said. We can see that this is an effect of the echoic memory, that <u>has stored the last 3-4 seconds of your mom's lecture and you can repeat this even if you were not paying attention. </u>
If you have samples of n 1 equals 22 and n 2 equals 20, in performing the pooled-variance t test, you have 40 degrees of freedom.
The t-test method is a method where we analyze two sets of data which both these data are independent of each other. This pooled variance test helps us in getting the overall variance in both these different sample sets when we know that both the sample sets are almost equal.
To calculate degrees of freedom, we have the formula
df = n1 +n2 -2
According to the question, n1= 22 and n2= 20
Therefore, degree of freedom= 22 +20 -2 = 40
Hence, degree of freedom is 40.

Reliable
<span>Reliable data and studies are those which consistently give the same results despite variance in time, location or setting. An example of reliability is when an individual gives the same answer to a question in the day time as well as nighttime.
Reliability and replicability are crucial requirements for research studies to be valid and credible. </span>

The Constitution was originally composed only of laws known as articles. Laws introduced later to the Constitution are known as amendments.
