Step-by-step explanation:
In adding fractions, first you have to make the denominators the same. To do this, you need to find the GCF (greatest common factor).
3/4 + 4/8
The GCF on this would be 8, since both 4 and 8 can go into it. Next, you need to change both the denominators to the GCF, but you have to make sure the fractions are still equal to the original one. To do this, you have to multiply the numerator by the amount the original denominator is multiplied to get to the GCF.
4(2) = 8
3(2) = 6
So now you have 6/8 + 4/8. Next, you just add up the numbers normally, leaving the denominators the same.
6/8 + 4/8 = 10/8
If necessary, you simplify the fraction. To do this, you need to find the smallest number that goes into both of them, besides one. In this case, it would be 2. Then, you divide both the numerator and denominator by that number.
10/2 = 5
8/2 = 4
Then, to find the most simplified version, you need to divide the numorator by the denominator.
5/4 = 1 with a remainder of 1.
You put your answer as the whole number, and your remainder as the numorator. Leave the denominator the same.

In constructing 98% confidence intervals for means, it is true that the statistic is good enough, and is less uncertain.
<h3>What is a confidence interval?</h3>
A confidence interval expresses the degree of uncertainty surrounding a given statistic. A margin of error is frequently used with confidence intervals. It reveals the degree to which you may be certain that the findings of a poll or survey correspond to what you would anticipate discovering if it were possible to poll the complete population. Levels of confidence are inextricably linked to confidence intervals.
Your level of confidence in your findings is shown by the confidence interval. You can never be certain that your results will hold for future surveys or experiments. In statistics, being 95% or 98.5% certain is typically seen as "good enough."

Answer:
7/8
Step-by-step explanation:
turn 1/4 denominator into 8 and by doing that, u multiply by 2.
whatever you do to the bottom, u do to the top. so 1/4= 2/8
5/8+2/8= 7/8
