State, and briefly explain, whether the width of a confidence interval for one population proportion would decrease, increase, o

Semenov [28]

Answer:

<h3>The option b) is correct</h3><h3>The width of a confidence interval for one population proportion would decrease, increase, or remain the same as a result is <u>Increase the value of the sample mean (0.5 point) </u></h3>

Step-by-step explanation:

Given that the width of a confidence interval for one population proportion would decrease, increase, or remains the same.

<h3>To find the result for the given data :</h3>

By definition we have that "the width for the confidence interval decreases as the sample size increases". The width of the confidence interval increases as same as the standard deviation also increases. The width increases as the confidence level increases between (0.5 towards 0.99999 - stronger).

The width of a confidence interval is affected by 3 measures. they are the value of the multiplier t* , the standard deviation s of the original data, and the sample size of n .

<h3>Therefore the width of a confidence interval for one population proportion would decrease, increase, or remain the same as a result is <u>Increase the value of the sample mean (0.5 point) </u></h3><h3>Therefore the option b) is correct</h3>

What is the quotient? Negative StartFraction 3 over 8 EndFraction divided by negative one-fourth WILL GIVE BRAINLIEST

Alisiya [41]

Answer:

Im not too sure given yopur formatting, but I believe you meant this: -((3/8)/(-1/4))

therfore, the answer is: 3/2

Step-by-step explanation:

You can seperate the two fractions as 3/8 divided by -1/4, which is equal to 3/8 * 4/-1, simply multiply across to get 12/-8, which simplifies to -3/2. Flip the sign to get 3/2

Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure of one of the four angles formed

vitfil [10]

We have
angle 1= $72 degrees$

see the attached picture to better understand the problem

we know that
<span>Vertical angles are congruent
</span> $angle1=angle3 \\ angle2=angle4$
<span>
and

adjacent angles are supplementary
</span> $angle2+angle1=180 \\ angle3+angle4=180$
<span>
if the measure of one of the angles is </span> $72$ degrees and straight lines equal $180$ <span> degrees you have to
subtract </span> $72$ from $180$
so
$angle 2=180-72 \\ angle 2=108 degrees$

therefore
$angle 3=amgle 1 \\ angle 3=72 degrees$

$angle 4=amgle 2 \\ angle 4=108 degrees$

the answer is

the measures of the other three angles are
$108, 108 and 72 degrees$
