Which of the following estimates at a 95% confidence level most likely comes from a small sample?
dusya [7]
<span>The <u>correct answer</u> is:

A) 60% ± 18%.

Explanation:

In a confidence interval, the margin of error is given by z*(</span>σ/√n<span>), where </span>σ<span> is the standard deviation and n is the sample size.

First we <u>find the value of z</u>:

We want a 95% confidence level; 95% = 95/100 = 0.95.

To find the z-score, we first subtract this from 1:
1-0.95 = 0.05.

Divide by 2:
0.05/2 = 0.025.

Subtract from 1 again:
1-0.025 = 0.975.

Using a z-table, we find this value in the middle of the table. The z-score that is associated with this value is 1.96.

Back to our formula for margin of error, we have 1.96(</span>σ<span>/</span>√n<span>). The larger n, the sample size, is, the larger its square root is. When we divide by a larger number, our answer is smaller; this gives us a smaller margin of error.

This means that if we had a small sample size, we would divide by a smaller number, making our margin of error larger. The largest margin of error we have in this question is 18%, so this is our correct answer.</span>

Graph the inequality. -8 &lt; y + 2x &lt; 14
kap26 [50]

Answer:

Step-by-step explanation:

Split it into 2 inequalities:

-8 < y + 2x

y + 2x < 14

Isolate y , subtract 2x from first and then from second

-8 -2x < y

y < 14 -2x

Rewrite it so it looks pretty?

y > -2x-8

y < -2x +14

You can use the calculator to graph each inequality.

The solution or the system is the area where the 2 solutions for each line overlap.

A farmer plowed a rectangular section of land for a new crop. The section measures 24 1/2 yd by 38 1/2 yd. Find the total area i
MAVERICK [17]

Answer: 943\dfrac{1}{4}\text{ sq. yds}

Step-by-step explanation:

Given ,  A farmer plowed a rectangular section of land for a new crop.

Dimensions of the section is given by :-

Length by width = 24\dfrac{1}{2}\text{ yd by }38\dfrac{1}{2}\text{ yd}

Since , the area of a rectangle = length x width

Then, the total area in yards of plowed section of land will be:

24\dfrac{1}{2}\times38\dfrac{1}{2}\text{ sq. yds}\\\\=\dfrac{2(24)+1}{2}\times\dfrac{2(38)+1}{2}\text{ sq. yds}\\\\=\dfrac{49}{2}\times\dfrac{77}{2}\text{ sq. yds}\\\\=\dfrac{3773}{4}\text{ sq. yds}\\\\=943\dfrac{1}{4}\text{ sq. yds}

Hence, the total area in yards of plowed section of land =  943\dfrac{1}{4}\text{ sq. yds}

Step-by-step explanation:

Total quantity of Liquid plant fertilizer=6 3/5 ounces

Quantity used up on a flower garden=2 1/2 ounces

Quantity of  liquid plant fertilizer are left=Total quantity of Liquid plant fertilizer -Quantity used up on a flower garden

6 3/5 ounces -2 1/2 ounces( subtract whole number from whole number and fraction from fraction)

6-2   3/5 - 1/2

4   (6-5) / 10

4 1/10 ounces of Liquid plant fertilizer left
