Step-by-step explanation:
First, we may wonder, what does the term <em>margin of error</em> mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.
It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to<em> increase the sample size</em> of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.
Answer:
0.25in.
Step-by-step explanation:
5÷20=0.25in.
<span>First, calculate the difference between 15 and 12. The operation, subtraction, will give us the answer of 3. Then, divide the calculated value by 12 since this it the theoretical length of the nail. Multiply the quotient by 100% to arrive to the final answer. That is (3/12)(100%). The final answer to this item is 25% which is the last choice. </span>
