A 95% confidence is given by (15,20) . The interval is based on a sample of size n=25 .
love history [14]

Answer:

b. quadruple the sample size.

Step-by-step explanation:

Given that a 95% confidence is given by (15,20) .

this implies that mean = average of lower and higher bounds of confidence interval = \frac{15+20}{2} =17.5

Margin of error = Upper bound - Mean = 20-17.5 = 2.5

Confidence level = 95%

Critical value = 1.96

Std  error = \frac{2.5}{1.96} =1.27551

Std devition = Std error * sqrt n = 6.3775

If we want to reduce margin of error by half we must get margin of error as 1.25

For that std error for same critical value = 0.63775

Std deviation did not change

So sample size only changed which implies that sample size is 4 times the original

b. quadruple the sample size.

An architect is sketching a blueprint of a patio for a new fence. On the blueprint, C is the midpoint of segment AD. Point B is
Gre4nikov [31]

Answer:

<u><em>The length of AD is 32 feet</em></u>

Step-by-step explanation:

<u>Proportional distances </u>

When distances are proportions of others, we can express all of them as relative fractions until we reach some known distance and solve for the desired length

Let's call x the length of AD. Given C is the midpoint of AD, then

\displaystyle AC=CD=\frac{x}{2}

Given B is the midpoint of AC, then

\displaystyle AB=BC=\frac{AC}{2}=\frac{x}{4}

If we know BC=8 feet

\displaystyle \frac{x}{4}=8\ feet

\displaystyle x=32\ feet

The length of AD is 32 feet
