Answer:
Reliable but not valid
Explanation:
Validity and reliability are two concepts in research study that is used for evaluating the quality of a research. They show how well a test, or a method measures something. Reliability is a measure of how consistent the test or measure is, while validity measures the accuracy level of the test or measure. In the example above, the measure is reliable, because the consistency of the result is not in doubt here, what is in doubt is how accurate the measure us. Here the respondents are unwilling to report unhappy feelings because they dont want to be judged, hence validity will be questioned here.
Answer:
An EMG may take 30 to 60 minutes.
Explanation:
Nerve impulses are extremely slow compared to the speed of electricity, where electric current can flow on the order of 50–99% of the speed of light; however, it is very fast compared to the speed of blood flow, with some myelinated neurons conducting at speeds up to 120 m/s (432 km/h or 275 mph).
They will need 3 boxes of jellybeans.
There are 4 people and each of them wants 6 jellybeans.
The <u>total number of jellybeans needed </u>is therefore:
<em>= Number of people x jellybeans per person </em>
= 4 x 6
= 24 jellybeans
Each<u> box holds 8 jellybeans</u> so the number of boxes needed is:
<em>= Number of jellybeans required / jellybeans in one box </em>
= 24 / 8
= 3 boxes
The group will therefore needed 3 boxes of jellybeans to satisfy themselves.
