An example of the ratio 4:1 could be, in a school for every 4 girls there is 1 boy. Or something similar:)
Answer:
4.969696 hours
Step-by-step explanation:
The distance traveled is shown through the following equations
Distance = velocity * time
This means that
4100=velocity*4
This means that ariplane 1 travles at 1025 km/hr
We can then subtract 200 from this to find that airplane two travels at a speed of 825 km/hr
Now we need to find how long it takes for that plane to travel 4100
So using the same equation
4100=825*time
Divison will tell us that the answer is around 4.9696 hours which is pretty much 5
Based on the given data the margin of error for the sample population is 6.15. This is computed based on the formula of margin of error for a sample proportion which states that the margin of error (z) is = squareroot of ((p(p-1))) divided by n, where p is the sample and n is the population. with that formula z = sqrt ((44x43)/50), z = 6.15
Changing from Two-sigma limits to three-sigma limits helps to reduce the probability that defects will be generated by the process. Hence the correct answer is C.
<h3>
What is a Two-Sigma Limit?</h3>
This is used to refer to the inclusion of about ninety-five percent of data plotted on the normal distribution curve.
Three sigma-limit on the other hand is a statistical calculation where data fall within three standard deviations from a mean.
If in a manufacturing firm, the quality control unit issues out a polity to reject products that are within two standard deviations to their accepted mean, then more errors will be captured thus resulting in a lot of loss or defective products.
