Answer:
Paired test
Step-by-step explanation:
The above research is carried out using a set of participants who were used to gather data under two different conditions. When this type of research is performed there is a match between the two conditions based on the subjects used, hence, we can pair the condition with the subject to obtain a matched pair. This sort of test also called the dependent sample t test. Thses type of test is ideal when the data is quantitative and the data obtained from two groups are dependent.
Professor Dan Healy, one of my Engineering instructors back in prehistoric times, had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it. Here is Prof. Healy's method.
For a few moments, call the square root of 5 by the name "cow".
cow - x = 4 . Solve this equation for 'x' :
Add 'x' to each side of the equation: cow = 4 + x
Subtract 4 from each side: cow - 4 = x
Now, we can put the real value back in place of 'cow' : <u>√5 - 4 = x</u>
That right there is a perfect solution. But If you absolutely need to
know the number, then grab your calculator:
√5 = 2.2361 (rounded)
x = √5 - 4 = 2.2361 - 4 = <u>-1.7639</u> (rounded)
Answer:
2<x<3
Step-by-step explanation:
the first one
Answer:
it is more like, 4x4=16
16x4=64
Step-by-step explanation:
I know it can be confusing, but you will eventually get it :)
i think you were adding 4+4+4=12, but that is not what you are supposed to do here.
Hope i helped :)
