Information about the proportion of a sample that agrees with a certain statement is given below. Use StatKey or other technolog
nydimaria [60]

Answer:

Answer is given below.

Step-by-step explanation:

Number of people, n = 400

Number of people who agree with the statement is 112.

Number of people who disagree with the statement is 288

Using Stat Key, follow the steps below to obtain the 95% confidence interval for the

proportion of the population to agree with the statement.

1) Open  

2) Click on CI for single proportion.

3) Click Edit data key.

4) Enter 112 in count text box.

5) Enter 400 in Sample size text box.

6) Click two-tail.

7) Click Generate 1000 samples key.

Output:  (See Image).

Original Sample

Count   SampleSize    Proportion

112       400       0.280

Bootstrap Sample

Count SampleSize Proportion

128    400        0.320

From the above dot plot , it can be observed that the standard error shows top right corner.

Thus the standard error is 0.022.

From the output, the 95% confidence interval is 0.2371 to 0.325

Write the equation of the circle with center (0,0) and (-1,-3) a point on the circle
saw5 [17]

Answer:

Equation of given circle :-  x² + y² = 4

Step-by-step explanation:

The equation of the circle with center (0, 0) and radius r is given by,

x² + y² = r²

It is given that, a  circle with center (0,0) and (-1,-3) a point on the circle

To find the radius of circle

radius r = √[(0 - - 1)² + (0 - -3)²] =√(1 + 3) =√4 = ±2

r = 2

<u>To find the equation of circle</u>

x² + y² = r²

x² + y² = 2²

x² + y² = 4
