The 95% margin of error simony states that there is a 95% probability that the confidence interval contains the true population mean.
<h3>What is a margin of error?</h3>
It should be noted that the margin of error simply means a measurement that accounts for the difference between the actual result and the projected result in a survey sample.
In this case, the 95% margin of error simply states that there is a 95% probability that the confidence interval contains the true population mean. This is the radius of the 95% confidence interval.

Answer: 1.2 10x ^3
Step-by-step explanation:
No it is not correct the answer is 14!
Answer:
4/5
Step-by-step explanation:
formula for slope is (y2-y1)/(x2-x1)
The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
